DL06/DL260 H0-ECOM and H0-ECOM100 Modbus TCP

Hello everyone,

I got stuck on Communication with DL06/DL260 (H0_ECOM or ECOM100) through Modbus TCP. To make it simple I only read holding registers, the same program on the computer can read Do-more PLC (H2-DM1E) and Productivity PLC (P2-550) without a problem, but when I try to read DL06 or DL260, it fails to get response. All those PLCs are working well in a network and one HMI can read all those PLCs, so it is not a hardware or wiring issue.

Any ideas? Is there any settings need to be do on the DL series PLC? I did not make any settings on Do-more or Productivity and they both work.

BTW, how could i find out or reset the IP adress of a H0-ECOM100 card? I forgot the IP I set before.

Thanks for any help.
