Issue:
I got a "Slave Device Failure" Modbus exception when I read the Embedded Configuration Registers for a Smartlink device.

Resolution:
Embedded Configuration Registers for a Smartlink must by read with a block of 64 Registers

Example:

• for Channel_1 - Input 1 => you need to poll 64 registers from Register 20010
• for Channel_1 - Input 2 => you need to poll 64 registers from Register 20074
• for Channel_7 - Input 2 => you need to poll 64 registers from Register 20778
