The communication description by the PmaCommGroup objects

The PmaCommGroup objects can be used for this driver.

The variables in the PmaCommGroup object (or even better the variables in the PmaData object with ExtComm data extension) can be of arbitrary number, type and order. The driver uses optimalised internal communication messages for reading the data from the device.

All variables are read (if the 'Data refresh enabled' configurator is checked). When writing to the variable, only the single value is sent (if the 'Auto send when writing to item' configurator is checked).

Description of the 'ItemID' configurator:

ItemId is the text identifier of the item that is used for addressing the value in the device. The ItemID configurator tells the driver how to receive or send the item value.

The text can be written manually, or it can be assembled in the window opened by the button to the right of the configurator.

Macro expression can be used for input (it is evaluated after starting the application).

The identifier consists of mandatory and optional parts.

- The mandatory part is the 'device' name (X,WX,DWX, ., C,WC,DWC, RT,DRT, ., D,DD) and numeric index.

- The optional parts are:

- The .S text can be entered at the end means that the variable (only for registers RT, RC, R, D) is a signed number.

Examples:

Slave5.DR100.S = It concerns the register R100 that is treated as 32-bit signed variable. The register is located in the PLC on the address 5.

DR100.S = Same as the previous example, but the address is detected from the 'Default PLC address' configurator.

DR100 = Same as the previous example, but the value is unsigned.

Description of the 'PmaCommGroup > Parameters > Special Parameters' configurator:

Default PLC address	The address defined here can be used for definitions in the 'ItemID' configurator for the variables in this object (i.e. the variables on the 'Data' page or in the ExtComm data extensions). The address can be entered in ItemID: - as for example Slave3.D6 - then the value will be read from the PLC device with address 3. - or not defined, i.e. D6 - and the address is taken from this configurator. This parameter can be modified and read in the script during runtime by methods: SetSpecParam('SlaveAddr') and GetSpecParam('SlaveAddr').

Default PLC address

The address defined here can be used for definitions in the 'ItemID' configurator for the variables in this object (i.e. the variables on the 'Data' page or in the ExtComm data extensions). The address can be entered in ItemID:

- as for example Slave3.D6 - then the value will be read from the PLC device with address 3.

- or not defined, i.e. D6 - and the address is taken from this configurator.

This parameter can be modified and read in the script during runtime by methods: SetSpecParam('SlaveAddr') and GetSpecParam('SlaveAddr').
