Hello, I am not familiar with the Omron PLC's. A PC is connected to the peripheral port of an CJ1M CPU12 PLC. The write command the PC is transmitting to the PLC looks like this (ASCII): "@00WD0070010055*." Can you tell me what kind of communication protocol it is using? It is a public or proprietary protocol? Thank you!

Hello everybody, I have CJ2M-CPU35 connected to couple of devices over ethernet IP. I would like to know which bits in CIO area (25 words for built-in E.Net port starting at 1500) gives me the status of Individual nodes (i.e. connected or not connected) Tried to go through W465 but there is a lot of information and I'm getting confused with built-in port, additional E.net IP units, Fins TCP, Fins UDP etc.

Hi All. I have a problem with D memory area. I have PLC CJ2M with ID211(DC input), ID211, OC211 (Relay output), OD212 (Transistor output) on the CPU rack. When I turn on all outputs in the OC211, all my datas in the D memory area is set to 0. What could be the problem? plc_project.zip

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

Tricky Communication in between RTU and SCADA Front End Processor
SESA218461 posted a topic in General Topics - The Lounge
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! -
Intermitent stop reading due to cable induction in cp1w
sergio garcia posted a topic in CX-Programmer
Im trying to control a baldor VFD trough modbus RTU with cp1h/cp1wcif12 using the solution posted here which for me works really fine but the problem comes when I turn on the motor (500hp 440v), the cable gets induced and adds noise to the communication causing errors when reading. I already try to use shielded cable and it gets better but still causing errors. In the solution posted in the link above shows how to connect the cp1w-cif12 by connecting only SDA- and SDB+. So my question is, should I connect FG to the VFD rs-485 ground as well to reduce that noise? Any suggestions are welcome -
