Hi! I have in my system a SM43-J-R20 PLC and A Frequency Inverter from Vacuum (Schmersal). I jus want to show the frequency of the motor on HMI. Think in using I6 as analog in, i did the JP8 and JP9 both to B (current) The thing is, I don't kwon how to wire it. See the manuals below. PLC/HMI Frequency Inverter Manual Terminal 18 (Analog Out) Terminal 5 (GND) Terminal 13 (Digital Out Comum) Anyone can help me? Thanks!

Hello. I try to use an Unitronics V200-unit (on a 570) 4-20mA output to operate a Samson 4-20mA-operated positioner. To start this positioner I must have 5 V across input (-impedance). When I use a Fluke 4-20mA simulator these 5V is generated at 3.8mA. When I connect the V200 to the positioner I must send between 8 and 9 mA to aquire the same 5V. This is a big problem!! Can anybody tell me how to solve this?
