9.1 Communication
Communication with two controllers (two drivers)
You can activate two different drivers in the terminal. This means the terminal is capable
of simultaneously communicating with two different controllers.
You can connect the controllers to the serial terminal interface, or to the PFE11A
expansion card via ETHERNET connection.
Signal addressing to the controller takes place according to the usual procedure for the
relevant controllers (see driver documentation for more details).
Call up [File] / [Project settings] from the menu in HMI-Builder.
Select the controller by clicking [Change] for system 1 or system 2. If the driver
selected for system 1 does not support two drivers, then you cannot select a driver
for system 2.
Click [OK].
Call up [Setup] / [Peripherals].
Drag [Controller 1] and [Controller 2] to th e connection ports to which the respective
controller is connected. Available interfaces are RS-232C, RS-422, RS-485
(DOP11A-30) as well as the PFP11A and PFE11A expansion cards.
Refer to the driver documentation for more details on how to connect controller and
terminal.
Addressing Signal addressing to the controller takes place according to the usual procedure for the
respective controller (see driver documentation for more details). To define the controller
to which a created object should be linked, click the button for the required controller
([1] or [2]) in the tool bar in HMI-Builder.
Controller 1 is set by default when you create or open a project.
Clicking the [1] button links the signal of an object to be created with controller 1. Clicking
the [2] button links the signal of an object to be created with controller 2.
Instead, you can also click the [I/O] button in the object to be created and select the
object to be linked to the controller using the I/O browser.
To address a signal in controller 2 when controller 1 is preset, add "@2" to the signal (or
vice versa "@1" for controller 1 if controller 2 is preset).
Example
Controller 1 is preset. Register D0 in controller 2 is to be linked to a slider. Enter "D0@2"
under analog signal in the slider dialog.
