There are two possible procedures.
1. First place the main element
Load a PLC main module at the position on the circuit diagram where you wish to have your PLC overview. If you place it by clicking once with the left mouse button, the database selection will appear.
In the database selection, pick out the corresponding PLC main module according to the item number.
In the symbol parameters for the main module, extend the Text2 by the address number. By doing this, you provisionally specify the addressing (e.g.!sps-byte10.0).
then assign the auxiliary element
Load a PLC auxiliary element symbol (input or output) at the position on the circuit diagram where you require it. Position it by double clicking with the mouse or by pressing the space bar (or abort the database selection with <Esc>). The list of all of the modules being used by the PLC Manager will appear. Select a module and then you can immediately assign the free channel of the module.
2. First place a virtual auxiliary element
Load a PLC auxiliary element symbol (input or output) at the position on the circuit diagram where you need it. If you place it by clicking once with the left mouse button, the database selection will appear.
If this channel is the first channel of a PLC module, pick out the corresponding PLC main module in the database selection. In so doing, you will specify the symbol of the PLC main module which is loaded virtually, analysed and managed from then on by the PLC Manager.
In the Symbol parameters for the auxiliary element, extend the Text2 by the address number. By doing this, you specify the addressing provisionally.
Assign the current channel to an Input/Output from the list of the main element.
Switch to Plc text in the Symbol parameters (click on the auxiliary element with the right mouse button) and the cursor will position itself automatically on the first available PLC connection pin.
When you confirm the connection, you will be prompted (depending on the wildcard present in the symbol) to enter the comment text and/or a symbol text.
then assign a virtual main element to a symbol
Load a symbol of the PLC main module and position it by double clicking with the mouse. A list of all of the main modules managed by the PLC Manager (including the virtual ones) will then appear. Assign the main module to the corresponding list entry (modules which have already been assigned are identified by !* at the end). All of the cross references are created and the PLC texts displayed automatically. Work in this way until the main symbol has been loaded for all of the PLC modules being managed.
Important
A symbol of the same name must be present in the library for each entry of a PLC main module in your item database.
Rule of thumb
The PLC Manager creates a new module every time you make a selection in the database dialog. This does not depend on whether you just load a main or auxiliary module. Skipping (double click or space bar) or cancelling the database selection always leads to an assignment.
