Hi,

I am working on a project in Digi Module ConnectME9210 and sending data to Allen Bradley PLC (CompactLogix 5370 family). I am not sure which endian I should use to send data. Does Allen Bradley receive Data in Big Endian or Little Endian?Also, What about Siemens data order? does it depend on PLC type?

I have another question as well. Can I make an EDS file to tell the PLC to receive data in UINT16, not as a single byte?

this also can be a correct place to ask your questions about PLC
