Fig. 4-5: How to operate the CAGE CLAMP g1xxx10x The WAGO-I/O-SYSTEM 752 requires a 24 V DC supply. The sensors supply voltage is short circuit protected by means of the plug-in fuse F1 (TR 5 / 250 V / 6.3A T).
Installation • 15 4.2.3 Connection of the Input Signals The input signal connection group is identified by the imprint “INPUT” on the base module. Three terminals are available for each digital input. The termi- nals for one input are shown superimposed in Fig. 4.7. Vertical connection group for one channel Color Input...
16 • Installation 4.2.4 Connection of the Output Supply Voltage The supply voltage for the two output groups of 8 connections each can be provided either internally using the supply voltage for the module, or exter- nally from a separate power source. The base modules are provided with two sets of terminal blocks in the middle row of the output terminals.
If more than 6 Amps is applied to the common terminals, separate terminal blocks should be used. Connect all common connections to the terminal blocks, and then connect the 752 common to the terminal blocks. This row of terminal blocks will be wired back to the source common of the supply poten- tial.

24 • INTERBUS 7 INTERBUS 7.1 Overview INTERBUS is standardized in the EN 50 254 as a fieldbus. Its architecture is that of a data ring with a central bus master and bus slaves. The INTERBUS differentiates among several sub-variants, two fieldbus vari- ants of which should be mentioned for the decentralized periphery: •...
26 • INTERBUS The INTERBUS transmission log can be understood as a large shift register. Each slave, with its input and output data, bus position, and data width, is an integral part of this shift register. Input and output data are processed simulta- neously during a scan cycle.
INTERBUS • 27 7.3 Process Image and Diagnostic Status Bits The process image is masked into the INTERBUS log word by word. Abbreviations Meaning Status of the digital input “x” Status of the digital output “x” Diagnostic status bit for the output group “x” Word 0 (in) 1.
Before a PLC can communicate I/O data with a fieldbus device, the fieldbus controller board has to be configured for each field bus device on the network. To accomplish this, the WAGO-I/O-SYSTEM 758 fieldbus controller board is delivered with WAGO NETCON software for configuring and diagnosing fieldbus networks.
