Connection between two controllers (cable 1 in Fig. 4-4):
• Connect the cable shield with terminal 89 (direct PE) of one fieldbus module and terminal 88
(capacitive PE) of the other fieldbus module (Fig. 4-5).
This method prevents currents flowing through the cable screens.
• Connect the terminals 71 and 72 between the fieldbus modules via paired cables (e.B. green
and yellow).
Direct connection to the host (cable 2a in Fig. 4-4)
• Connect the host cable screen to PE and the controller cable screen to terminal 88.
This method prevents currents flowing through the cable screens.
Connection to the 201IB interface converter (cable 2b in Fig. 4-4):
