Specifies the number of poll attempts to be skipped before trying to re-establish communications with a slave that has failed to respond to a command within the time limit set by the Response Timeout parameter. After the slave fails to respond, the master skips sending commands that should have been sent to the slave until the number of skipped commands matches the value entered in this parameter. This creates a sort of slow poll mode for slaves that are experiencing communication problems. Inter-character Timeout 0 to 65535 milliseconds Specifies a time delay in milliseconds to be added to the 3.5 character time delay used by the module to recognize the end of a message. Certain applications may require validation of Modbus messages with more than 3.5 character time between consecutive bytes (example: modem applications). A value of 0 causes the default end of message delay to be used Command Error Offset -1 to 9998 Sets the address in the module’s database where the command error data is placed. If the value is set to -1, the data is not 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 are copied to the database as follows: 1000: error code for command 0 1001: error code for command 1 … An error code of 0 means that the command was successfully sent (no error).
Additional Configuration Parameters as Slave The Type parameter must be SLAVE or PASSTHRU SLAVE to configure these parameters. See Configuration Parameters Common to Master and Slave (page 40). Parameter Value Description Minimum Response Delay 0 to 65535 milliseconds Sets the number of milliseconds to wait before responding to a command received on the port from a remote Master. This delay is sometimes required to accommodate slower Master devices. Internal Slave ID 1 to 247 Defines the Slave Node 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. Bit Input Offset 0 to 9999 Specifies the offset address into the internal Modbus database for network requests for Modbus function 2 commands. For example, if you set the value to 150, an address request of 0 returns the value at register 150 in the database.
Word Input Offset 0 to 9998 Specifies the offset address into the internal Modbus database for network requests for Modbus function 4 commands. For example, if you set the value to 150, an address request of 0 returns the value at register 150 in the database. Output Offset 0 to 9998 Specifies the offset address into the internal Modbus database for network requests for Modbus function 1, 5 or 15 commands. For example, if you set the value to 100, an address request of 0 corresponds to register 100 in the database. Holding Register Offset 0 to 9998 Specifies the offset address in the internal Modbus database for network requests for Modbus function 3, 6, or 16 commands. For example, if you set the value to 50, a request for address 0 corresponds to the register 50 in the database.
