Input Word Em.1 "Consumption" [Consumption]; Input Word Em.2 "Pressure P2" [Pressure P2] - Festo MSE6-E2M Original Instructions Manual

6 Input/output data
6.2.3

Input word Em.1 "Consumption" [Consumption]

The input word is shown in Motorola format (MSB-LSB).
Depending on the parameterised air consumption unit and the parameterised flow standard, the air
consumption measured is transferred to the higher-order controller as the input word (2 bytes, 16 bits).
The presetting of the module parameter "Unit Consumption" is "l", the presetting of the module para­
meter "Unit Flow standard" is "DIN 1343". Independent of the parameterised unit, the maximum con­
sumption value displayed is 65535. If there is a change to the parameter values "Flow unit" or "Flow
standard", the consumption is reset to the value "0". If there is a change to the parameter value "Con­
sumption unit", the consumption value remains unchanged and is converted correspondingly.

6.2.4

Input word Em.2 "Pressure P2" [Pressure P2]

The input word is shown in Motorola format (MSB-LSB).
Depending on the parameterised pressure unit, the pressure P2 is transferred to the higher-order con­
troller as the input word (2 bytes, 16 bits).
The presetting of the module parameter "Unit Pressure" is "mbar". The input word is always specified
in the data format "Sign + 15 bits". The pressure value is stored in the input word as follows.
