[Section]/Item Value
Range
Description
Minimum Command Delay:
0 to 65535 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.
Command Error Pointer:
-1 to 4999
This parameter sets the address in the internal 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.
Response Timeout:
0 to 65535 This parameter represents the message response timeout
period in 1 ms increments. This is the time that a client 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.
Retry Count:
0 to 25
This parameter specifies the number of times a command
will be retried if it fails.
The command list for the client in the module is located in the [ ] section of the
file. The following table describes the functions supported by the module and the
format of each command:
Parameter Range
Description
Enable
0 ,1,2
This field defines whether or not the command is to be executed and under
what conditions.
Value
Description
0
The command is disabled and will not be executed in the
normal polling sequence.
1
The command is executed each scan of the command list if
the Poll Interval Time is set to zero. If the Poll Interval time is
set, the command will be executed, when the interval timer
expires.
2
The command will execute only if the internal data associated
with the command changes. This value is valid only for write
commands.
Internal Address 0 to 4999
This field specifies the internal database register to be associated with the
command.
- If the command is a read function, the data read from the Server device will
be placed starting at the register value entered in this field.
- If the command is a write function, the data written to the Server device will
be sourced from the address specified.
