I'm trying to get this software to log data from a twido TWDLMDA20DRT which I've ethernet enabled using the twidoport 499TWD01100 ethernet module. I've had this same software working find with a momentum PLC but can't get it to function with this setup. The error I recive is 1 Query sent to slave and no responce within poll interval. Has any one used this software before. I can get a demo of kepservers modbus TCP opc server to talk ok but this is three times the price of modicoms Simple TCP logger. http://eclipse.modicon.com/ look under Networking support to see the software I'm trying to get working.
Simple Modbus TCP logger
- Thread starter ISL_MAN
- Start date
As usual soon as I post on here I find the solution myself by accident I may add. I've had to use hyperterminal to reconfigure the twidoport unit's gateway configuration. I've changed the Slave address Source from UNIT_ID to FIXED with a slave address of 1 which happens to by my PLC modbus address. I then had to put 1 in the bridge option on the Simple Modbus TCP logger program and it started working.
