The following parameters are required only if the port is to be configured as a

Master.

ENQ Delay : 0 #0-65535 milliseconds before DLE-ENQ sent

This parameter specifies the number of milliseconds to wait after a DLE-ACK is

received from a slave using half-duplex mode before the DLE-ENQ request is

made for data. Enter a value in the range of 0 to 65535 milliseconds.

6.3.2 Minimum Command Delay

This parameter specifies the number of milliseconds to wait between issuing

each command. This delay value is not applied to retries.

6.3.3 Error Delay Count

Error Delay Count : 100 #0-65535 Command cycle count if error

This parameter specifies the number of polls to be skipped on the slave before

trying to re-establish communications. After the slave fails to respond, the master

will skip commands to be sent to the slave the number of times entered in this

parameter. Enter a value in the range of 0 to 65535.

6.3.4 Command Error Pointer

Command Error Pointer : 3000 #Cmd Error list data (-1=ignore)

This parameter sets the address in the internal database where the command

to the database. Enter a value from 0 to 4999.

6.3.5 Slave List Pointer

Slave List Pointer : 3100 #Slave status list data (-1=ignore)

This parameter specifies the starting address in the virtual database where the

256 slave status values will be written. If the parameter is set to -1, the slave data

will not be placed in the database. Enter a value in the range of -1 to 4743.
