Connecting plug-in modules
The TX700 HMIs allow the use of several optional in modules. Several module configurations
are possible.
Fig. 13: Slots for plug-in modules
Slot 2 and slot 4 are available only if the plug-in module has bus extension connector.
Each slot has three communication channels:

1 SPI interface
NOTE
It is not possible to stack two modules that are using the same type of interface.
The following table shows, which plug-in module and how many plug-in modules can be used
at which device:
