File M0 Offset Register Content Description
N10:52 53 5052 Minimum
Response Delay This parameter sets the number of milliseconds to wait
before a response message is sent out of the port. This
parameter is required when interfacing to a slow
responding device. Enter a value in the range of 0 to
65535.
N10:53 54 5053 Use CTS Line This parameter specifies if the CTS modem control line
is to be used. If the parameter is set to 0, the CTS line
will not be monitored. If the parameter is set to 1, the
CTS line will be monitored and must be high before the
module will send data. Normally, this parameter is
required when half-duplex modems are used for
communication (2-wire).
N10:54 55 5054 Slave ID This parameter defines the virtual Modbus slave
address for the internal database. Any requests
received by the port with this address will be processed
by the module. Verify that each device has a unique
address on the network.
N10:55 56 5055 Bit Input 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.
N10:56 57 5056 Word Input Offset This parameter specifies the offset address in the
internal Modbus database for network requests 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.
N10:57 58 5057 Output 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
return the value at register 100 in the database.
N10:58 59 5058 Holding Register
Offset
This parameter specifies the offset address in the
internal Modbus database for network requests for
Modbus 3, 6, or 16 commands. For example, if the
value is set to 50, an address request of 0 will return
the value at register 50 in the database.
N10:59 60 5059 Command Count This parameter specifies the number of commands to
be processed for the port. Enter a value of 0 to 100.
N10:60 61 5060 Minimum
Command Delay This parameter specifies the number of milliseconds to
wait between the initial issuance of a command. This
parameter can be used to delay all commands sent to
slaves to avoid "flooding" commands on the network.
This parameter does not affect retries of a command as
they will be issued when failure is recognized. Enter a
value in the range of 0 to 65535.
N10:61 62 5061 Command Error
Pointer
This parameter sets the address in the internal Modbus
database where the command error data will be placed.
If the value is set to -1, the data will not be transferred
to the database. Enter a value of 0 to 4999.
