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
n
n+1
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
n
n+1
n+2
n+3
n+4
n+5
n+6
n+7
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)
