Input/output (I/O) modules
5-101
Combined analogue I/O modules with galvanic isolation
Signification of the I/O words of a PCD2/3.W525 module?
When configuring a W525 module using the Device Configurator or the Profi-S-I/O
(or Profibus DP) Network Configurator, the PCD2/3.W525 does need two registers for
the analogue outputs and 8 registers for the analogue inputs.
The significations of the registers are the following:
Output registers:
Register
Bit 31..16
Bit 15..0
n
Value CH0 Output
n+1
Value CH1 Output
Description of the output registers:
Value CH0..1 (Register n, n+1)
This registers (Bit 0 to 15) does contain the analogue output value of the correspond-
ing analogue output. It’s a 12 Bit value.
Input registers:
Register
Bit 31..16
Bit 15..0
n
Value CH0 Input
n+1
Value CH1 Input
n+2
Value CH2 Input
n+3
Value CH3 Input
n+4
Load Current/Voltage
n+5
Status Module
n+6
Status Input
n+7
Status Output
Description of the input registers:
Value CH0..CH3 (Register n...n+3)
This registers (Bit 0 to 15) does contain the analogue input value of the correspond-
ing analogue input. It’s a 14 Bit value.
Load_Current / Load_Voltage (Register n+4)
On this register (Bit 0 to 15) the actual current or voltage value is displayed.
■
current in [μA] (0..20’000)
■
voltage in [mV] (0..10’000)
