Support Questions / DataSubscriber2

« on: August 11, 2018, 09:19:45 AM »

Anyone have experience with the datasubscriber 2 as used in v35
It appears to be an enhanced version of the subscriber with multiple PLC addresses instead of one, anyone know how to use this in addition how the number of elements works

I would like to read a bunch of 2 consecutive group register groups from an omron PLC via serial link.

Regards

Support Questions / Omron PLC BCD double register read

« on: August 01, 2018, 09:41:34 PM »

Hello Guys
Quick question I am trying to read a BCD value from an omron CQM1 PLC via RS232 port, I have found that the BCD value is spread across two consecutive 'DM' registers each, containing 4 digits. I can use a label in advanced HMI to display each of the registers individually however before I do some sort of code to join these together then display I would like to know if there is a way for advanced hmi to read these values and display them correctly without code.

I have tried using 'LDXXXX' instead of just DXXXX but these two options show the same result.

Regards

Ah yes Archie got it working so there is hope yet, back to the drawing board.

What driver are you using?

I can try with a serial port sniffer to see what were getting back from the PLC next time I visit this site. I write to multiple 'D' resisters without error as well as I can read HRXX.XX but not write to it so I am thinking it maybe driver related. I would have loved to hear that this was successfully done by someone already to know that it is not actually an advanced HMI driver issue.

I tried HRXX.XX and HXX.XX, with HRXX.XX I get an error string format incorrect, with HXX.XX I don't get any error but the write is not working. I have tried reading the status of HXX.XX to a text display and it works well the problem looks to be in writing to the PLC. I have even tried using code like Me.OMRONHOSTLINKDRIVERNAME.Write("HXX.XX",1) but still no effect.

Support Questions / Omron CQM1H PLC Holding Relay

Hello folks,

Recently I've encountered as failed obsolete HMI connected to an Omron CQM1H PLC, so decided to give advanced hmi a shot at replacing It. Since both PLC and original HMI programs are available no programming changes were required in the PLC. The advanced HMi displays were created with controls and mapped to required PLC addresses.

The application works and communicates perfectly except that I have not been able to write to the holding relays HRXX.XX. Folks can you offer some assistance here.

I should say that even though I have been doing PLC development for many years Omron is not the brand that I usually interact with.

Seeking some expert advice here.
