3.2.3 Modbus Port x Commands This section defines the master command list specifications for a Master port. The information in this section applies to both MBS PORT 1 and MBS PORT 2. In the ProSoft Configuration Builder tree view, double-click the MODBUS PORT X COMMANDS icon. In order to interface the MVI69E-MBS with Modbus slave devices, you must create a command list. The commands in the list specify the slave device to be addressed, the function to be performed (read or write), the data area in the device to interface with and the registers in the internal database to be associated with the device data. The Master command list supports up to 250 commands. The command list is processed from top (Command #0) to bottom. Read commands are executed without condition. You can set write commands to execute only if the data in the write command changes (Conditional Enable). If the register data values in the command have not changed since the command was last issued, the command is not executed. You can use this feature to optimize network performance. The MVI69E-MBS Master (and Slave) communication drivers support several data read and write commands. When a command is configured, the type of data (bit, 16-bit integer, 32-bit float, etc), and the level of Modbus support in the slave equipment needs to be considered.

Description Enable 0 to 4 This field defines whether the command is to be executed under certain conditions. Disabled (0) = The command is disabled and is not executed in the normal polling sequence. Continuous (1) = The command is executed each scan of the command list if the Poll Interval (see below) is set to zero. If the Poll Interval is set to a nonzero value, the command is executed when the interval timer expires. Conditional (2) = For write commands only. The command executes only if the internal data associated with the command changes. Bit/Word Override upon Error (3) = For read commands only. If a command error occurs, the module overrides the associated database area with the Override Value Upon Error parameter value. Float Override upon Error (4) = For read commands only. If a command error occurs, the module overrides the associated database area (2x word count) with the Override Value Upon Error parameter value.
