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.
