the same diagram, a FMS(product by FISCHER&PORTER), there are the terminals:V8,V9,X1,G2,+,-. the connection like this:
V9-----24V(power)
V8-----PI19.2/6ES5-420-4UR12
+(4-20ma)-------1/4(AE3) of the SIPART-6DR2004
-(4-20ma)-------ground.
the EMF instruction manual say that there is a Rb>=U/I between V9 and 24V.
I want to know the mean about the connection about V8 and V9.
