Output Offset
0 to 4999
This parameter specifies the offset address into the internal Modbus database for

network requests for Modbus function 1, 5 or 15 commands. For example, if the

value is set to 100, an address request of 0 will correspond to register 100 in the

database.

Hold Offset
0 to 4999
This parameter specifies the offset address in the internal Modbus database for

network requests for Modbus function 3, 6, or 16 commands. For example, if a

value of 50 is entered, a request for address 0 will correspond to the register 50

in the database.

Command Count
0 to 100
This parameter specifies the number of commands to be processed by the

Modbus Master port.

Minimum Command Delay
0 to 65535
This parameter specifies the number of milliseconds to wait between issuing

each command. This delay value is not applied to retries.

Command Error Pointer
-1 to 4899
This parameter sets the address in the internal Modbus database where the

command error will be placed. If the value is set to -1, the data will not be

transferred to the database. The valid range of values for this parameter is -1 to

4899. For example, if this parameter is configured for 1000, the command errors

will be copied to the database as follows:
1000: error code for command 0
1001: error code for command 1
and so on.
An error code of 0 means that the command was successfully sent (no error).

Refer to Status Data Definition for the command error code listings.
