  2. Hi! I have my 1756 IF8 wired in high speed differential mode but i can't configure the RTS smaller than 11 ms. What I understand it should be possible to set as low as 5 ms if module filter setting is 1000 Hz. Is there anything else that i have to do?
  3. Hi All I am new here without much experience of plcs. I have a PV 550 with DH485 coms port that I want to replace another PV550 with rs232 that communicated with an SLC 5/04. Is there some way to connect the two with a cable or protocol connector? Alternatively can you connect through the printer port on a PV600? CHeers   Azza

  5. I have a Micrologix 1400 and one PC which sends 102 Characters in RS-232. I need to read all characters with Micrologix 1400, Is there any way to read all characters? I know the limit of ARL and ARD instruction is 82 characters. I do not know if two ARD instructions could read all characters. Do you have any experienced like that? Could you help me? Thank you in advance

  6. CPU 948R

    Rifuath posted a topic in Siemens

    We have Redundant S5- CPU948R we have the requirement of knowing input address for FUM signals(Open & close signals).. Also how can we identify which cpu is acting as main CPU and which one is Standby. We look forward to a solution. Kindly advice us.
  7. Greetings, I've been having some issues with a vacuum pump breaker tripping... I think I've figured out the problem and resolved it but I noticed that several of the other motors have current monitoring on the HMI but the person who set this up is no longer with us.  I'm wondering what I need besides an analog input for my control logix processor (which I have) to setup this project.  I'm not sure if the other motors are just monitoring one leg of the 3 phases or if they are somehow showing total current?  any ideas and recommendations would be greatly appreciated.   thanks,

  10. Sending Ascii from PLC

    remspot posted a topic in CX-Programmer

    I have an omron cp1le plc and a sato s84ex printer I need to learn how to send print jobs to it. I know I can use the Serial card option and send the code to the printer over RS232. I am using the NiceLabel software and printing to file which extracts the SBL code. That is where I am stuck. What part of the code do I use and where do I put it in the CX-Programmer. And what instructions should I be learning to send Ascii to the printer. I am very new at all this and just want a few hinters and direction. Thanks.
  11. Hello! I am programming with FT view studio version 8. In the program, when I make numeric display, I can not input values for this tag I am using in the display. Then I decided to make 'invisible button' for enabling the input for this tag which is shown in the numeric display. This is okey for me, only if there is other ways to do this please tell me. Now when I have created this numeric display with input enabling -'group', I have a problem, how can I use security levels for this group, so that only logging in values can be set? I have found that there is security code selection for this in the screen displays, but not for the buttons.
  12. Hello Everyone, I want to have a serial communication using Siemens S7-1200 with CM 1241 (RS-232) and communicate with my Arduino. Here is the setup of the communication. I have 2 temperature sensor and one Led connected to my Arduino, and on the PLC side I have S7-1200 from Siemens and CM-1241. Arduino and my PLC are connected just by using Tx and Rx pin no handshake is done. I am sending the temperature data from both the sensor to the PLC. on the PLC side i decide when to turn on the Led connected to my arduino depending on the different temperature values. I have assigning a ID to both the sensors before sending out the data. This is how the transmitted data from Arduino looks like $AOPT_TEMP1_20_TEMP2_21 . So far its good, I am receiving serial data on my PLC using RCV_PTP (received data are placed on the buffer) and sending data using SEND_PTP. I have also implement a filter on the PLC which will only accepts the serial data starting with '$AOPT_'. Now, I want to receive the temperature value from two temperature sensor TEMP1 & TEMP2 and then control the Led. For instance if (TEMP1>TEMP2 ) then turn ON the Led else turn OFF. I am able to receive the data on the PLC from Arduino but now I don't know how to proceed with comparing the received information. How do i extract the only required data from the received buffer? Any suggestions will be highly appreciated. Thanks in advance....

  13. Rotary input device

    python01 posted a topic in Control Panel Building

    I am looking for some sort of rotary input device which could be used for fine adjustment. Ideally it would have to two output pins, if turned clockwise it would send pulses on one of the pins and when turned counterclockwise it would sent pulses on the other pin. These could be connected to two inputs on PLC and a value in a given variable could be incremented and decremented depending on the direction of rotation. Almost like using potentiometer with analog signal. I guess if I can not find anything I could use incremental encoder and look at the phase of the output to decide which way it is being turned but hopefully simpler and maybe more cost effective solution is out there? Thanks.
  14. Hello everybody, I am connecting my DCS digital output (115VAC) to AB PowerFlex 753 Digital Input. We are using the 20-750-2262D-2R I/O option in the powerflex which is 115VAC I/O with 2 Analog In, 2 Analog Out, 6 Digital In and 2 Relay Outputs. My question is, what is the current or power consumption of the PowerFlex DIs at 115VAC. I need to specify the right fuse size for my digital output. Thanks,
  15. I'm new to Omron, and after several days of diving into manuals trying to figure this out on my own and giving myself a headache I've come to accept that i need help. my task is the following: Control of the discrete and analog inputs/outputs in a DeviceNet system using an Omron CJ1M PLC’s and PT’s. Use at least one thermocouple, one analog input, and one analog output for the DeviceNet network. Use a pushbutton and a light for the start of the process and an indicator for the started process. I have a Drt1-Ad04 input, a Drt1-ad02 output, and a Drt1-ts04t temperature control. My devicenet is Cj1w-drm21, The Omron system itself is a cj1m-cpu13 etn21. I have node addresses for my input, outputs and temperature control, those being 35 for input, 25 or 30 for output and for temperature control 5, 15, or 20. The ip address im using for this project is 142.214.143.9I'm using Cx programmer, Designer and Integrator. On Cx programmer I've managed to create an IO table but i have no idea on how to begin the program or even get a current reading from my generator.On Designer I've made what i believe to be the layout of the pushbuttons, I just have no idea of what addresses to enter.And on integrator i'm having troubles on figuring out how to make a routing table. I've went through many manuals and either i'm missing something really basic here or I just have no idea on what I'm doing. The only advice I was given was to dive into more manuals and find my addresses for my inputs, outputs, and temperature or to find the information from an outside source be that a forum or customer service. I am able to provide more information, and screenshots of what I have done if needed. Any kind of help would be greatly appreciated!
  16. For "string display and input" objects, there a "full keyboard" option that, when selected, will cause a keyboard screen to pop-up when you press on the input object. Is it possible to change this keyboard to one with Russian characters on it?

  17. Connect OMRON CJ1H to GSM modem

    AlexCyril posted a topic in CX-Programmer

    Hello guys, actually I am new to this Omron PLC. but i have small project to transmit a command to the GSM modem via the RS232 port so it can trigger the modem to send text msg. Can you show me the steps/guide/sample program to accomplish this program coding? I already read some topic in this forum regarding to this PLC RS232 port but still cant get the ideas when to create the ladder program. PLC Type : CJ1H (CPU65H) - RS232 port First input to trigger the GSM send text msg: AT+CMGS="+YOUR HP NUMBER" Second input to trigger GSM send text msg: YOUR TEXT MSG CONTAINS (Ctrl+z to send) Many Thanks, AlexB
  18. I am working on Remote IO panel and plan to use the following components: 1734-AENT 1734-OW4 - qty 2 1734-IE4C I wonder if I need to separate the bus between the relay output module and analog input module? Or anywhere else in this setup? Thanks.
  19. I have the following situation; I have a distribution network connecting about 400 RTUs, using 101 protocol to connect to their PDH MUX, which data slot is transported using SDH STM-1/4, to the Primary Substations. Then the primary substations connect to the LDC building using STM-16. At the Control Centre Building where the Front End is located, there is a STM-16 node with some PDH ports, but definetly not 400, so how can I extract this 101 asyncronous data channels to connect them to the SCADA Front End? Note that conversion to 104 is not allowed by the client. Thanks in advance!

  20. Using GX Works 2

    raybbr posted a topic in Mitsubishi

    Hi all, Just joined today and was browsing through this forum. Now I need advice/help. I have installed the software to read an FX PLC. It worked okay yesterday. I was going through a program printout that I downloaded and couldn't see where the X inputs were in the program. So, I thought i'd go back in and get the program again. I connect to the FX fine. It passes the test and then I connect. The screen comes up entitled "Online Data Operation". I select "All" and hit the execute button. Wait about five seconds and then I get an error: "The Device Data Name is Empty". Okay. I go to put a name on the "Title" box and it WILL NOT TAKE KEYSTROKES. Gaack! :helpme: I have restarted the program and laptop several times. No matter what i do it will take keystrokes in the "Title" bar. I cannot get the program. Any thought? The only thing I can think of is to reload the program but that takes quite a while. Old stuff is fun to work on.
