Need a communication between Micrologix 1100 (Allan-Bradley) and SPPA-T1000 (Siemens) on Modbus. Please suggest the suitable communication procedure and accessories.

Hello Sanjib;

The only reference I find on the SPPA-T1000 and Modbus comes in the following document:

Unfortunately, it is not very technical. However on the last page there are contact names and numbers, so I suggest you get into contact with them.

Hope this helps,
Daniel Chartier

Please look at the MARC Omnii-Comm http://www.miille.com/din266-p00.pdf for this application. You may also consider the Omnii-Comm with Ethernet Port http://www.miille.com/266-P00-Ethernet.pdf that provides an Ethernet/IP compatible connection. Both modules can provide a connection between a MicroLogix and the Siemens using Modbus

The DataLink DL4000-DMX will interface your Micrologix CH0 DF1 to Modbus RTU.
