  1. Tia Portal Programming Help PLEASE

    Hello I am having some difficulty writing code for a specific function using Tia portal and a S7-1200. I 10 Digital inputs and 1 analogue output set for 0-10V. When 1 DI is high I need the AQ to be at 1V, when any 2 DIs are high I need the AQ to be at 2, When any 3 DIs are high I need the AQ to be at 3V and so on.... I just can't work out the best way to do achieve this.   For a bit more info the to what the project entails the digital inputs are all coming back from DOL starters for woodworking equipment at workstations. When one of these starters is turned on a signal is sent back to the PLC DI card, this open a solenoid in extraction pipework and also increases the frequency at a VSD to extract the dust. So when more workstations are in use the higher the frequency of the VSD will be and the faster the motor will run allowing adequate extraction at all stations

  4. Hello All I am new to sysmac studio, i am using a NJ301-1200  and R88M-KN10H servo drive , i connected the servo to the NJ using ethercat. I was able to write a program where i was able to activate the servo from the NJ using the mc_Power instruction . My question is , i am not able to run the servo using the mc_movevelocity and mc_moverelative . Do any one have any suggestion to how to go from here ..  
  5. S7-1200 timer

    Hi All I am struggling to get a TON in TIA v15 to work properly (s7_1212). I have tried reading what i can but still dont understand why what i have is not working.  I have attached a screen shot. I am trying to achieve a bit that is active for 1 scan cycle and resets every second. Coil1 is just staying active however and not resetting the timer.  What i have written works in Connected Components Workbench and other plc software i have used. What am i doing wrong? Thank you in advance. Trevor  
  6. Hello! I am using S7-1200 PLC 1212C AC/DC with configured Modbus TCP Server. I can already read/write Inputs/Outputs (Coils) and Memory Words. However I'd like to read/write Memory BITS. Is it possible? If so, how? What addresses should I use in TIA portal? And which function codes on client side? Thanks in advance!
  7. Hello! I am beginner in PLC world, also in SIEMENS PLCs. I managed communication over private network. Now I have a problem that I get same values on all inputs. Picture below shows my configuration of driver and data monitor. First picture shows values when input I0.0 is in state 0. Second picture shows values when input I0.0 is in state 1. Physically on PLC only input I0.0 is forced to 1, input I0.1 stays 0. But data monitor shows both inputs as state 1. Where is problem? Is problem in PLC program, TIA portal? I saw some guys using DataBlocks but I am not skilled enough to use it. Third picture shows simple PLC program on my PLC. Please help. Thanks in advance!
  8. Hello! I am trying to connect my PLC with SCADA. I am using S7-1200 1212C CPU (RELAY outputs). My SCADA system is iFIX 5.8 with driver S7A. I am trying to establish connection via GPRS router (TCP/IP). Port being used is 102 (default by S7A driver). In my company we have private network, SIM card in GPRS router gets static IP (set by RADIUS server)  which is 10.247.XXX.XXX. My PLC has IP 192.168.0.10 set in Project. I am not sure what am I doing wrong. How to correctly set IP address in PLC to communicate in private network via GPRS router with static IP? I already enabled TCP port 102 in my router but I am not sure to which IP should I enable it because I am not sure if IP address set in PLC is correct. Should I use some communication blocks in program? I also enabled PUT/GET function (see attached pictures). Please help. Thanks in advance! :)  
  9. Have a micrologix 1200R 1762-L40BWAR.  If anyone could help with providing the following information: Need a communication port with single receptacle that will mount through the door of electrical enclosure and then the communication cable (6 to 10') that will go from the com. port to the micrologix. Thanks
  10. Does anyone have an example piece of ladder logic, created on a Micrologix 1200, using ASCII to READ and Write to a serial device?  I am building a ladder on a Micrologix 1200 that will send data to an old CNC once a certain ASCII instruction is received on the PLC.  For example, when the machine spits out an ASCII "1", the PLC will see the "1" and send out a three digit number depending on a sequence of discrete inputs.   Thank you,
  11. Square Wave Problem With Micrologix

    Hello all, this is my first post. I am using an AB Micrologix 1400 (1766-L32BXB Ser C FW 21). I was trying to generate a pulse train using the PTO instruction. I have modified PTOX funct. file. The ladder is just a simple XIO followed by PTO, (The Quick Start ladder from 1766-RM001). When I looked at the output waveform on my oscilloscope, I noticed that it wasn't a square wave. I decided to run it at several different frequencies to see how the wave form would change. At 10Hz i got a square wave. As I increased the frequency the falling edge became sloped and almost horizontal. Is this how the output should behave? The data sheet indicates a max frequency of 100kHz, but at frequencies over 150 Hz. The wave form looks like the output of SMPS. 
  12. Hello, I'm new to PLC Programming, with just a simple course about the basics. I've got a micrologix 1400 PLC which seems to have had its program wiped when the battery was replaced. I've had the company that supplied the machine it runs send me the program for the PLC. However, I don't have any software to communicate with it, and download the program to the PLC. I was hoping some one here could help me out and direct me towards what I will need to do to get the new program installed on the PLC. Thank you 
  13. Hello I have a scenario that's been bugging me for some time now. The scenario consists of a Micrologix 1400 that I need to control it's output from modbus/tcp. In detail what I really need is to be able to manipulate the O0:0 through modbus/tcp. The PLC would be the master and I would be the slave that triggers the connection to the master. I'm using a Modbus-Client on my PC and that should be the slave. Any idea as to how I can manage that? Currently I can send data to the master but everything is "stored" on B10 and I have no idea how I could write directly on O0. Thanks a bunch guys. PS: I'm borderline noob. 
  14. Hi my problem may have a simple solution but i cant work it out. I need to use the Divide function but it wont let me use a decimal point in either Source A or Source B. Is there a way to use a decimal point in Logix 500 Math instructions? Im using an AB Micrologix 1400 PLC. Can you only use math instructions with whole numbers? is there a way around this? Thanks James

  17. Communication

    good evening. Someone can give tips on how to configure and physical the application with the following items: Advanced Interface Converters (AIC +), PanelView800 2711R-T7T A and MicroLogix 1500 Programmable Controllers My doubts are about the configuration of the communication, and I have doubts about the physical environment and protocol to be used.

  19. Hello :I'm the creator of an Android HMI app,  I recently added Ethernet/IP connectivity with MicroLogix and SLC AB PLCs, but I have only been able to test it with a MicroLogix 1100.I'm really not sure if it works with SLC or with other MicroLogix models.If someone could try it, I would appreciate it. To access the test, from the Android device, open this https://play.google.com/apps/testing/com.suppanel.suppanel on the web browser and install the Beta version.On the application you have to open the "EIP MicroLogic SLC Test" panel that contains some instructions. Thank you very much !
  20. Hello everybody. I need to learn PLC programming. I already have some experience with Ladder language and PLCSIM so now I need a real PLC to do more practice. I was going to buy the following unit: 6ES7211-1BE31-0XB0 http://www.eibmarkt.com/isroot/eibmarkt/Files/DatenblattE/NS6102812.pdf It has 6 Di, 4 DO (Relay) and 2 AI, that's more than enough for me to do some practice. Do you think it would be a good idea to buy it? Or maybe this PLC doesn't have some important component or device needed to work properly? (my company will give me the software). Thank you to anyone will help me. Have a nice day, Edoardo
  21. Micrologix 1400 Float TAG

    Hello,  I have a micrologix 1400 plc connected to a length measurement gauge. The gauge sends an analog value to the plc to an analog input. I convert the value into a dimension and send it to F8:0. but I need this value in three different steps in the program. Since i just have one element of float (F8:0) is there anyway i can store the value in a different location or create more floating point tags eg. F8:1. F8:2 ?    Thank You   
  22. Good evening(here at least),    I am working on a senior design project that requires the use of a PLC. Due to budget we've had to settle for an older Micrologix 1000 from Allen Bradley. I've managed to get the software running and connect with the programming port. The problem I have right now is trying to decipher how I would connect a load cell(Such that it causes a condition change at a certain weight). Ideally I would want a load cell amplifier connected to an analog input, but I don't think the 1000 has support for that. Would it be possible to use something like the HX711 amplifier(digital output) to be read on one of the input pins of the micrologix? I wanna say the pins don't read a pulse modulated input and I can't seem to register for the AB knowledgebase as the site gives me a web error. I'd appreciate any feedback.  Thanks in advance.

  24. HELP! Wiring 1214C DC/DC/DC CPU

    I am currently finishing my A.S. in Engineering Technology.  My Capstone course is to wire up a complete S7-1200 system using a 1214C DC/DC/DC CPU.  There have been no courses that have explained exactly how they are wired.  Only programming, which I am pretty good with.  There is a 120VAC to 24VDC power supply.  They want it to be wired to switches and lights for a simulator.  I am just not sure exactly how the I/O's are wired.  Is is sinked or sourced?  As far as I know, one sends the ground to the output, and one sends the 24v to the output.  I would love to speak with someone on how to wire this, as once I graduate, this is what I want to be doing, but I am stuck in a hard place as none of my classes taught us how to wire the PLC's and even worse, the programming class was all about AB PLC's.  I have not learned about Siemen's at all.  They should be pretty close to the same, but I know there has to be some differences.  Also, how they have it set up, there are 2 power supplies on the plastic panel just to the left of the picture.  This seems to me as this is a sinking I/O.  Am i off?
