Configuring the Modbus Client Read Command
The Modbus Read Command reads 10 words of data from the Quantum
processor (Modbus Slave) and transfers it to the MVI56E-MNETC module's
internal database. The following table describes the relationship between
memory addresses in the Modbus Master (MVI56E-MNETC) and the Modbus
Slave (Quantum processor).

disabled. To enable the command, change the E
shown in the following illustration.
Notes:
FC 3 represents Modbus Function Code 3, the command code to Read Holding Registers
The DevAddress parameter is 0-based so 800 = 400801, 801 = 400802, and so on.
The Enable code must be set to 1 to enable the command (0 = disable)
The destination Slave node address must be set as 1 (Node parameter)
