IO configuration

This module is used to configure the IO modules.

General

For this purpose, an interface is added first, and the IO modules are then attached to this interface. To add an interface, click on the "+" symbol and select an appropriate interface from the menu. To add an IO module, right click on the interface and select an IO module from the menu.

The interface R02 has a special position. This interface is intended for the pluggable IO modules, i.e. the internal bus system. To change the parameters of a module, click with the right mouse button on the module and select Parameter from the menu. The parameters are described in the documentation of the IO modules.

Interfaces

The following interfaces can be added:

M-R02 Control unit: This interface refers to the internal bus system; only modules of type 2020 can be added here.
M-B01 Control unit RTU: Bus coupler with RS485 interface, only modules of type 2020 can be added here
M-B02 Control unit TCP: Bus coupler with network interface. In addition to the pluggable IO modules, fieldbus modules can also be added via the gateway function.
M-FBM Fieldbus IO Interface: RS485 interface on the controller (R02, Tauris), only fieldbus modules can be added here.

IO modules

M2020: Pluggable IO modules on R02/B01/B02.
Fieldbus: Fieldbus modules with Modbus RTU interface.

After the interfaces and IO modules have been added, click on "Create all variables" to create the corresponding variables.

Parameter Interface

Active	Activate interface. If the interface is not active, neither the interface is initialized nor are the attached IO modules queried.
Telegram distance	This distance is at least maintained between telegrams. Normally the standard settings entered when adding the interface can be used.
Timeout	Maximum time to wait for an answer from the IO module until an error is detected and the next query begins.
ID	Modbus ID. This is only specified for Bus Coupler B01/02.
Serial interface / TCP gateway	For the fieldbus interface and B01, either serial interface, if the module is connected directly to the R02, or Modbus TCP gateway, if a B02 is used as gateway, can be set.
Commport	The serial interface can be specified here (with R02 only onboard possible).
Baudrate	Baud rate for the serial interface
IP Address	With the setting Modbus TCP Gateway the IP address is set here.

Parameter IO Module

Active	IO Modul aktivieren. Ist das IO Modul nicht aktiv, wird es bei der Kommunikation übersprungen.
Priority	A priority can be set for each module. With this function the communication speed can be influenced. The individual modules at an interface are read out one after the other, with priority 0 each module is read out at every cycle, with priority 1 at every second cycle and so on. This is useful, for example, if there are analog inputs on the bus that change relatively infrequently, and digital modules that should be read out more quickly, in which case you can give the analog module priority 100, for example, and the digital module priority 0. This means that digital module 100 is read out and then the digital module once.
