  1. Hi everyone, I want to receive signal  from E+H flow sensor to Rockwell PLC( module MVI69-HART attached to PLC). I tried to use local 4 which is new local opened when I added successfully MVI69-HART(INT type variable) but it not work. Sensor's monitor display mA values (4mA -> 20mA).  Could you please show me how to receive mA signal in PLC software or give me some documents related to this issue?  Thanks. Have a nice day. ^^
  2. Gentleman…   Does Rockwell have any simulation PLC code that mimics an SMC-Flex soft starter?  Since we are using those (as well as the E3+ and E300) I would like to develop a model environment for starting of several drives.  In a specific case, we may have 3 or 4 drives in a pool of drives in which only a subset must be running at any one time.  Development of ladder logic for starting and maintaining those drives running while considering various fault conditions and startup issues would be very helpful in our environment.  I would like to be consistent among various areas within our plant that we incorporate pools of drives, from 4 to 2.  Having the ability to test in the lab would be very beneficial.  Thank you, David
  3. Hello there. I have connected wireless module (master) to Vijeo Citect 7.4 using RS-485 to USB converter. My slave modules are supplied power from gird/generator and the master module is supplies from a UPS.    I'm reading Modbus registers of slaves modules data via wireless master. Every time we have a power failure from grid, I get #BAD from all slave addresses. The generator kicks off within 30 sec. That is the slaves are off for 30 sec. Even after the slaves are powered on, SCADA does not poll data from it until I restart the SCADA.    My current MODBUS parameters are:   Inittype = 3, TimeOut = 3000, WatchTime = 10, Retry = 2. Could you please assist me on which parameters to change in .ini so that SCADA reads Modbus registers of slave for more than 30 sec.   I tried increasing TimeOut to 30000 but it couldn't solve the problem. I would appreciate if some one could help me out.   Thanak you in advance.

  6. Modbus TCP Data Logging to Database

    gclshortt posted a topic in HMI & SCADA

    Here is a recent post that I would like to share. Using Visual Basic 2015 we will log three holding registers from the PLC along with time and date into a Microsoft Access Database. We will log every minute into the database with the information that we collect from the PLC via Modbus TCP (Ethernet). All code will be done and shown so you can implement this in your application with different parameters. The information collected in the database can then be distributed or analyzed in the future. Visual Basic 2015 will be used with the EasyModbusTCP client/server library for .net. We will communicate to an Automation Direct – Do-More PLC. Using the free simulation software of the PLC Designer Software, we will retrieve three values of the Modbus Holding Registers using Modbus TCP. Once we have this information out of the programmable logic controller it will be placed in a Microsoft Access (2010) Database. This will be done by using a SQL command to insert the data. Read the rest of the post... Let me know what you think, Thank you Garry http://accautomation.ca/

  9. Hi all,    Its the first time in this forum and need help about slc05/05 processor and modbus RS485. We need to link one slc05/05 with 5 power analysers and 3 vfd all with rs485 modbus rtu ports, as i now the slc05/05 have RS232 that suports Modbus, can we put an converter RS232 to RS485 and put slc05/05 to read write the power analyser's and vfd's. There are any sample / step by step tuturial with modbus and slc05/05 ?   Best regards, Jorge Cruz

  12. CP1E MODBUS Maximum Slave

    innoaloe posted a topic in Omron

    Hello everyone, so I noticed in Omron's CP1E manual, there are no certain info on maximum number of Modbus Slaves that can be attached, however the PLC itself able to connect to slave number 1 - 247 I have read from common MODBUS specs, that 32 slaves are the limit for most MODBUS connections. However there are also statements that with proper design (1/8 transceivers) that we can extend number of connected slaves to 256. Anyone have experience or info about this with Omron PLC? Thanks in advance
  13. Dear Professionals, I am new in AB PLC, but I know Siemens PLCs. I must learn AB and I appreciate any help regarding below basic questions: 1) What is the OS (Firmware) in AB PLC? Is there any OS commands concerning AB programming? 2)How does AB PLC execute the program in the cpu? ( in Siemens PLC, there are OB( organization Blocks) to write logic program and OB1 executes cyclically and therefore, any block which  is called in OB1 is executed by the cpu cyclically as well. Can we compare it to AB?) 3)How is the structure inside AB CPU concerning the RAM (different areas in the RAM for user program and OS etc), Micro-Processor, Memory Card etc 4)How AB PLC reads/writes IOs from the I/O modules? is there any Image area in the RAM for digital IOs ? how about analog IOs? As I am very new in AB programming, some of above questions may look silly, but any guide is highly appreciated. I need to start from somewhere :) Thanks     
  14. I need to learn about position control for 2 axis with a QD75MH2 module. I know how the basics about programming with the Q Series PLC but I've never done any positioning control. I'm having a really hard time understanding the program I have to modify and I don't know where to start. Is there any course you might recommend? Even if I have to pay for it. Thanks.

  17. Newbie Help, Migrating from Allen Bradley

    RoyLittle0 posted a topic in Siemens

    Hi all, I am currently looking migrating from a company that works solely with Allen Bradley to a company that works mainly with Siemens, at the moment its Step7 for the PLC and TIA Portal for the HMI, but they will be moving to TIA for both PLC and HMI, I have worked with Allen Bradley for over 9 years PLC5, SLC500, 5000 and control Logix, the company will be providing me with a full training package but that wont be for about 5-6 weeks, can anyone point me in the direction of any good training material to get me started with a head start before I get the training, there seems to be more on Allen Bradley than Siemens. Video's preferably so I can watch them in my hotel room whilst working away, also any tips on the differences between Allen Bradley and Siemens

  22. I need to know if there is an easy way to convert a hex value to ascii without going through all of the math. In the ContolLogix 5000 software, I can find how to do a string to decimal (STOD), but the problem is the initial value. For example, the hex value for ASCII 3 is 31, ASCII 4 is hex 32, etc... If I do a STOD to create a string from the value of hex 31, I get a string of: '31'. I need to send this value out to hyperterminal and read a 3, not 31. If it was only reading one source and did a simple subtract and mov commands for the values of 0 through 9, that would not be a problem. However, my problem is that I am continuously reading multiple valuses from several sources and I don't want to have to write the code for each character from each source. I could do and AOI or UDT, but isn't there a simple instruction in the logic?
