Connecting ETG1000 and TWIDO TWDLCEA40 through Modbus

Q

Hi everyone,

We are working on a project that needs to communicate between module TSX ETG1000 and a TWIDO controller TWDLCEA40DRF through Modbus Protocol. We have directly connected them by using a RJ45 cable (by default: port 4-B, 5-A and 8-Ground). Using web browser (that locates to Web Server inside the module ETG1000), we have already read memory values of ETG 1000, but cannot read any thing from the TWIDO controller.

PS: In project we use WebDesigner (Schneider Electric) to add Twido controller as Other Device/Other IEC into the Target.

What is the matter here? Any suggestion will be appreciated. We need help instantly.

Thanks for regard.
