     It is possible to use the interrupt inputs (Int0 = i 8100; Int1 = i 8101) of a PCD2.M5xxx or PCD3.Mxxxx as normal input without using the corresponding interrupt XOB.

662. Why are the inputs and outputs of a PCD3 systems not switched on and off correctly, or switched on and off randomly, or the I/O status not detected correctly in the PLC?

     The problem may be related to a loose contact on the PCD3.K010 connectors used to connect the PCD3.M/Txxx CPU's and the PCD3.Cxxx expansion modules.

663. Why can't I change the Profi-S-Bus address on a PCD3.M6540 Port 2?

     While the serial PGU port of systems before the PCD3 did always work as PGU port when connecting a PCD8.K111, the serial PGU port of the PCD3 can be configured for using a modem. If this is done, it is no longer possible attaching a PCD8.K111 and establishing a PGU connection.

665. Why can't I read data from a CALEC aquametro energy master device?

     1%

     In order to read data from "CALEC aquameter energy master" devices using the F27x modules (except PCD2.F2700 or PCD3.F270) the M-Bus FBox library 2.6.117 or later is required.

666. Why do I get a "DUART HW ERROR" on PCD2.M150 after restart?

     Communication on port 3 (PCD2.F520) during startup can lead to a DUART HW ERROR on the PCD2.M150

667. Why do I get the error "Missing value" when reading some M-Bus devices?

     Relevance:

      

     1%

     When reading values from some specific M-Bus devices with the M-Bus modules PCD2/3.F27xx, the M-Bus driver may show the error "Missing value" even though all values are correctly returned by the device.

668. Why do I get wrong values when reading a PCD2/3.W340 with media mapping?

     Relevance:

      

     1%

     PCD2.M5xx0 and the PCD3.Mxxx0 systems equipped with firmware 1.10.16 did not correctly calculate the temperature values of NI1000 temperature sensors measured with PCD2/3.W340 input modules.

669. Why do some M-Bus devices not work on all ports of a PCD2.M5 or a PCD3?

     Relevance:

      

     1%

     Some M-Bus devices (so far only observed on a MBus water counter from the company Allmess / Actris) are very sensitive against inter-character delays.

670. Why does Windows find a new USB device for every PCD?

     If a PCD is connected to the PC via USB cable, the new firmware PCD3 V010 and PCD2.M480 V020 do send a unique ID in their StringVendorRequest (iSerialNumber). This has to be done this way because it's the only way to distinguish between several devices with the same VID/PID (VendorID/ProductID) in a USB bus system.
