Slot and port assignment on the

display

• Inputs are assigned to measuring channels in the

ascending order of the slots and ports.

Adjacent example:

"CH1: 1:1 pH glass" means:

Channel 1 (CH1) is slot 1 (basic module) : Port 1 (input

1), pH glass sensor

• Outputs and relays are named according to their

function, e.g. "current output", and are displayed in

ascending order with the slot and port numbers

Order of the modules

Depending on the version ordered, the device is supplied with a number of electronic modules, which

are assigned in a specific sequence in ascending order to slots 0 to 7. If you do not have a particular

module, the next moves up automatically:

• The basic module (which is always present) always occupies slots 0 and 1

• Fieldbus module 485

• Photometer module PEM

• Memosens input module 2DS (DS = digital sensor)

• Extension module for digital inputs and outputs DIO (DIO = digital input and output)

• Current input module 2AI (AI = analog input)

• Current output modules 4AO or 2AO (AO = analog output)

• Relay modules AOR, 4R or 2R (AOR = analog output + relay, R = relay)

With intrinsically safe sensor communication module 2DS Ex-i:

• CM442/CM442R: always in slot 2

• CM444/CM444R: always in slot 7 (two channel) and slot 6 (four channel)

• CM448/CM448: slot 7, 6, 5

Modules with 4 ports are connected before modules of the same type with 2 ports.
