Register Content Description
10,054 Slave ID This parameter defines the virtual Modbus Slave
address for the internal database. All requests
received by the port with this address are
processed by the module. Verify that each device
has a unique address on a network. Valid range for
this parameter is 1 to 255 (247 on some networks).
10,055 Bit in Offset This parameter specifies the offset address in the
internal Modbus database for network requests for
Modbus Function 2 commands. For example, if the
value is set to 150, an address request of 0 will
return the value at register 150 in the database.
10,056 Word in Offset This parameter specifies the offset address in the
internal Modbus database for network request for
Modbus function 4 commands. For example, if the
value is set to 150, an address request of 0 will
return the value at register 150 in the database.
10,057 Out in Offset This parameter specifies the offset address in 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.
10,058 Holding Reg Offset 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.
10,059 Command Count This parameter specifies the number of commands
to be processed by the Modbus Master Port.
10,060 Minimum Command
Delay This parameter specifies the number of
milliseconds to wait between issuing each
command. This delay value is not applied to
retries.
10,061 Command Error Pointer 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 9675.
10,062 Response Timeout This parameter represents the message response
timeout period in 1-millisecond increments. This is
the time that a port configured as a Master will wait
before re-transmitting a command if no response is
received from the addressed Slave. The value is
set depending upon the communication network
used and the expected response time of the
slowest device on the network.
10,063 Retry Count This parameter specifies the number of times a
command will be retried if it fails. If the Master Port
does not receive a response after the last retry, the
Slave devices communication will be suspended
on the port for Error Delay Counter scans.
