AI signal transfer to another PLC
I have one Analog input which i used to measure material level.
Now my question is i want use this same analog siganal to the other PLC to see this same material level on that HMI.
How can i do it?
What i try that this AI signal i add in the hardware at AO channel. But during download time hardware error is come.
If the other PLC is of ABB Advant Controller 400 brand you can use CI855 communication interface for MB300.
Then we're left with fieldbuses like ModbusTCP, MODBUS, COMLI, etc as much preferred (safe, secure and pricy) options.
4..20mA analog loop is also very safe & secure but less desirable due to interference and need of close/small geometry.
I understand that you have opted for this but I wanted to bring you some other options...
If you need help with a download error - please bring us the details of the error
Your very last option is to involve Microsoft and "Level 2" systems ... namely OPC DA...
OPC is by far the most unreliable & insecure but cheapest method to transfer data between two different brands of PLCs.
The Property Transfer service in System 800xA can act as an "OPC DA relay" but is subject to the (often poor) write performance of the receiving OPC server, then add all that DCOM mess and complex firewall configuration on top of that (if the transfer should be considered "secure"), then finally put the glaze on in the form of Windows Update, McAfee Update, scheduled outages & maintenance, e.g. for backups, etc.
