Combination of PXC4, PXC5.E24, and PXC7 with TXM modules

General

General aspects
TXS power supply modules for TXM modules	For calculation of the necessary TXS power supply modules, see TXM I/O modules
Panel layout	Devices	Dimensions L x W x H
	PXC4... PXC5.E003 PXC5.E24 PXC7...	124 x 198 x 70 mm 124 x 144 x 70 mm 124 x 270 x 70 mm 124 x 198 x 70 mm

	TXM1... I/O modules	64 x 98 x 70 mm
	TXS1.12... power supply module TXS1.EF bus connection module	96 x 98 x 70 mm 32 x 98 x 70 mm
	TXA1.IBE Island bus expansion module	32 x 98 x 70 mm
Limitation in the number of TXM modules	The PXC4 and PXC7 automation stations support two communication modes for the TXM modules:
	Polling mode (default mode)	Support of up to 64 TXM modules per automation station
	Event mode	Support of up to 8 TXM modules per automation station
