M2400
The M2400 is an analog output box with up to four channels, which also has two digital data bytes. The box jumpers determine whether the data bytes function as input or output bytes (see M2400 manual). If the box has less than four analog channels, the corresponding DACs are not linked.
 | Data telegram only for the higher priority task If the box is linked to several tasks (e.g. DACs with NC and data bytes with PLC), the data telegram is only created for the higher priority task. This is particularly important during commissioning if, for example, only the PLC is running. |
Context menu
Add Box...
Adds another box above the marked box.
Delete Box... <Del>
Deletes the marked box and its sub-elements from the I/O configuration.
Import Box...
Adds another box above the marked box. The description of the new box and its sub-elements are read from a file with the suffix "*.tce". This file is created with the following menu option.
Export Box...
Exports the information from the selected box and the information about its sub-elements into a file with the suffix "*.ioe".
Variables
Four 16 bit output variables with the descriptors DAC 1 to DAC 4 are created and can be linked. Both data bytes are located correspondingly under inputs and/or outputs. The orientation is entered in the ”Data Bytes” tab. The data bytes can be accessed as both bytes and bits.
"DAC's" tab
The individual variables can be linked for all variables via the ”DACs” and ”Data Bytes” tabs. You can of course still create the links using the context menu or the tab view for each variable.
DAC 1...: Opens the link dialogue for the first analogue output channel.
DAC 2...: ditto...
”Data Bytes” tab
D 2...: Opens the link dialogue for the first data byte (D2 in the telegram).
Input / Output: Determines whether the data byte is treated as an input or output (must correspond to the hardware setting).
By bytes / by bits: Determines whether the link dialogue is opened for the whole byte or for individual bits.
