Hey All, I have run into an issue where my CJ2H-CPU64 EIP cannot communicate over EIP To the nodes connected. This machine in particular was running just fine previously. I have replaced all ethernet cables and the Hub as well.(8-port unmanged) I can ping all the nodes that are connected. But i cannot ping the PLC in question. I can connect directly to the PLC but not over ethernet. So i changed the PLC out thinking it was a bad port but the problem is the same on the new plc. Any Ideas? Thanks in advance Richard

Hi Bob, 1. Yes i have the address changed to what i needed. I have downloaded my configurator file to the plc as well. 2. I have the devices isolated locally. only 3 devices that can communicate with it (I can ping all of them) 3. Yes, Currently plugged in that way.

Hello All, I have a problem within 2 PLC's here in my plant. Both are CJ2H-CPU64-EIP. They are running almost identical programs just different lines. When the problem occurs the PLC drops out. I get no alarm on the PLC. But when I start to recover from the drop it has caused all D Memory to be 0 and I lose protocol macro settings within the SCU Card attach to the PLC. Has anyone ever had a similar issue. If so is there an easy fix? Thanks for you support

To further this issue.... I get an I/O bus error when it happens. The manuals are very unclear for these issues. Code 80CF/0F0F IO Bus error F

The parameters that are being changed can be accessed at the HMI ( NS10 and NS8 ) both using ethernet connectivity. Basically if for example someone changes the allowable tolerance for a press force or distance i need to make the management aware of the change.

Good Afternoon Everyone, I know this topic of Sending an Email from a PLC has been touched on before: I have been tasked with trying to send email from a CJ2H-CPU64-EIP. I want to know if that is even possible or if there is a better route such as SMS. I need to be able to alert the right people when a certain set of parameters changes. It can be slightly generic as a message but i need to include the person whom actually did the change ( that comes from RFID Badge Login ). Any Ideas please let me know or Send an example. Thank you Ahead of time for any help.

No SCADA attached to the PLC.

All, I am trying to use a new item (MicroADM from CWT) that requires rs485 to rs232 connection to pc or whatever needs to communicate at that end(the unit has the converter connected inline). I am trying to connect the unit to a CJ1W-SCU21-V1. The programming that I am using is the the ModbusPM v5 that I downloaded here. I need to be able to read the coils(func 01) and registers(func 03). If i do a trace on the Protocol Macro Software I can see that I am sending the correct message but I get no return message or response. I am not sure is it is my cable pinout. If I connect my usb to rs232 to the 485 to 232 convertor I can get connected with Multiway( modbus) and send the same message but i get a response. My wiring for this is attached. any help will be much apreciated Thanks

Do you have pin 4/5 on PLC side wired? Try to jump them at PLC side.

Jay, thanks for reply. I am using pin 9 as signal ground. I have tried a few different configurations and still no reply.
