UNFguy (Customer) asked a question.
I'm having trouble with getting my Weintek CMT3072x HMI and BX-DM1-10ED2-D. I have followed the guide from maple systems on how to configure the HMI for connection to PLC however, I continue to get the "no PLC response" message on the HMI. Help?
Can you provide some screenshots of both the HMI and BRX configurations? Also what address in the PLC you are trying to access?
Looks like you are communicating via RS-232? What are your serial port settings for the Do-More CPU?
Can you verify you have your wiring correct?
Are you getting any transmit or receive lights on either the panel or Do-more CPU?
Yes, according the documentation from maple systems I needed to connect the HMI to the PLC via RS-232/J12 cable. With RS-232 coming from the HMI and the J12 connector going into the ethernet port of the PLC. However, when connected I do not see any lights come on that indicate communication at the ethernet port on the BRX PLC. The only settings that I have personally configured are in the screenshots I have added.
Are there other parameters that should be configured in order establish a connection using the RS-232/J12 cable?
You should be connected to the RS232 port on the front of the PLC. Not the ethernet port.
Your original post indicates that you're working with a BX-DM1-10ED2-D, which does not have an Ethernet port. However, the latest image from your System Configuration shows an IP address and Subnet Mask for the Internal Ethernet Port Configuration. The CPU Configuration also indicates that the selected CPU in the project is a BX-DM1E-x.
The Ethernet port on a BX-DM1E-x is an RJ45 connector, rather than an RJ12 connector, and is used for Ethernet communication, not Serial communication. If you're using RS-232 communication between the HMII and the BRX, you should be using the 3-pin RS-232/485 terminal block on the PLC to make connections between the PLC and HMI. Hopefully, this gets you moving in the right direction.
Yes sorry about that I was playing around with the idea that the PLC previously mentioned, not new, might have been just been old so I tried a different model. However, I do think you may be correct about the ethernet port. I assumed that since the J12 and ethernet heads were similar that the port would be able to read the J12 connector. An oversight on my part. The options I am looking at now are getting a serial POM module for the J12 connector, or connecting to the RS-232 port above.
Thanks for the advice.
