Hi Alekhandro, I am interested in becoming a contact programmer for you. I will stay local though. Neo

Hi Chris, Sorry for a late response. I have not logged in for a while. I' ve been busy. I don't have the PLC available any more. I gave them away. I am sure you can find them on Ebay. Neo

Anyone in need of SLC 150 AB PLC. I have three working ones. Let me know.

I have tried all the combinations in the PLC setting dialogs of CQM1 and CJ1M but i can only tranfer data from cqm1 to cj1m but not the other way around. I ran out of idea, please help.

I use the TXD-RXD CS/CJ program that you posted. The setting for end code in the plc set up is 0x000D. One thing i notice is as soon as i turn on the InitiateComm bit 0.01, the Port Ready Flag turns off right the way. This does not happen in CQM1. I have to turn off power of the CJM1 and turn it back on to turn the Port Ready Flag on.

I only got it to work in sending from CQM1 to CJ1M. It does not work if i send from CJ1M to CQM1. I tried everything. Please help

Do i need to download the program to both CJ1M plc and CQM1 plc. I tried that but i did not work. I also tried to download to just CJ1M but it didn't work. The same is for CQM1. I set the parameters according to the setting stated in the program. What did i do wrong?

Hi all, I want to use TXD and RXD instructions to send and receive data to and from CJ1M to CQM1. How do I set up CJ1M and CQM1. I want to send data through RS232 not Peripheral port. Could anyone send me an example. Please help. Thank you very much.

What is the shorted logic to move input bits to HR bits as below: 1.0 TO H1.1 1.1 TO H2.1 1.2 TO H3.1 1.3 TO H4.1 1.4 TO H5.1 1.5 TO H6.1 1.6 TO H1.2 1.7 TO H2.2 1.8 TO H3.2 1.9 TO H4.2 1.10 TO H5.2 1.11 TO H6.2 And 2.0 TO H1.10 2.1 TO H2.10 2.2 TO H3.10 2.3 TO H4.10 2.4 TO H5.10 2.5 TO H6.10 2.6 TO H1.11 2.7 TO H2.11 2.8 TO H3.11 2.9 TO H4.11 2.10 TO H5.11 2.11 TO H6.11 Please help sending me a code sample. Thanks

Could you show me an example. I am using CQM1 CPU41

Hi all, I have 5 input words that i use. How can i create a loop to scan 16 bits of the first input word then go back and scan the next input word bit by bit and so on until 5 words are scanned. Base on the condition of these bits the program will do something. How can i set indirect addressing for IO instead of DM area Please help
