2.6 [IEC-103 Master Commands]
This section can contain up to 1000 user defined commands to be executed by
the module and sent to the controlled devices. There is no need to place Class 1
or Class 2 polls in this list for the controlled devices as the Master driver for each
port will execute these automatically when the port is idle. In order for the port to
be idle, make sure that there is idle time available, and that the commands do not
constantly utilize the ports. The command list section starts with a reserved label
START and ends with the label END. Each row in the file corresponds to an
individual command with the first character position in each row left blank (white
space).
As an alternative to using a command list, blocks with an identification code of
9901 can be used to issue commands from the ladder logic.
2.6.1 Enable Code
0 = Disabled
1 = Enabled, will execute using Poll Interval parameter (page 40) (seconds)
2 = Conditional (executed when point in database changes)
This field defines whether the command is to be executed, and under what
conditions. To disable the command, set this parameter to 0 (Disabled). You can
still execute commands through the processor, using a Special Function block.
To enable the command, set this parameter to 1.
 Set the Poll Interval Time to 0 to execute the command during each scan of
the command list.
 Set the Poll Interval Time to a value in seconds, to execute the command at
the specified interval (page 40).
To execute the command only if the internal data associated with the command
changes, set this parameter to 2. This value is valid only for write commands.
2.6.2 Database Index
Database Index is the location in the module's database to use as the source for
the data in the command. Refer to Data Type for specific information on
addressing (page 41).
