Allen Bradley and Siemens PLCs data order

[mhdazeem]

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?

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?
