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.
