Variable data types and transfer to AB plc via Ethernet/IP

Print Friendly and PDF

Products: ACR9000, 9030, 9040, 9600, 9630, 9640, Aries Controller (AR-xxCE)

ACR controller user parameters/variables are listed below:

 

Note user parameters P0 - P4095 are 64-bit floats. If using Ethernet/IP to transfer data to these variables from an Allen Bradley/Rockwell plc:

CIP Class1 messages data transmitted to the PLC with always be represented as DINT data type regardless of the actual data sent.

example:  If p1=10.0 on the ACR it will show as hex 4120000 on the PLC.

Use COP function to move this from the HEX/DINT form into a real to convert it to 10.0

For further details:
