Group send function with Modbus RTU & ICP Gateway

Postby om_tech_support_JT » Fri Feb 26, 2016 6:27 pm

Q: I am using one of your FLEX products and I am looking to do a group send message via Modbus however my ModBUS master controller will not allow this? I am using the ICP gateway from Ethernet IP to ModBUS and it will not allow for group send message. Can you provide any solution?

A: You can assign each driver its own address number. Then assign group commands of the same number to the drivers which you wish to group. To do this use Group Register 0030h (upper) 0031h (lower). To execute the group use Function code 10h (writing to multiple resgiers) and use the address which you assigned the group.

However, please refer to the specific user manual for your Flex product.
