. Why the Modbus communication over Ethernet between a Saia PCD and a Siemens S7-314C-2 does not work correctly? (FAQ #101973) Situation: The PCD is configured as Modbus client with the Saia-Modbus client F-Boxes and you have to communicate over Ethernet with a Siemens S7-314C-2 with the Modbus protocol. Randomly, some read or [...] use the card PCD3.F281, it is recommanded to install the library Belimo 2.5.301 or a later version. You can find these libraries on the support site. The path is: Software -> PG5 -> FBox libraries

When more than 1 displays of the same type (PCD7.D23x and PCD7.D290) are connected to a RS 485 port (Bus terminal) of a PCDx.F2xx module, the communication doesn't work. Only one of the displays is available, the other one(s) is (are) not accessible!
Building Automation and Control Network BACnet/IP support for PCD1.M2, PCD2.M5 or PCD3 systems can be added by mounting a BACnet module PCD7.R56x (or PCD3.R56x). This module contains a firmware [...] modules PCD2.F2610 (for PCD1.M2 and PCD2.M5) or the PCD3.F261 (for PCD3.M and PCD3.T666) allow a direct connection to the DALI bus as DALI master, programmed with FBoxes. With one module up to 64 ballasts [...] library is provided together with PG5 Controls Suite. As KNX/EIB is a slow bus, about 200 to 300 points per connected gateway/KNX (EIB) line can be handled by a PCD. A full RS 232 or an Ethernet port

inputs. To fill this gap we offer interrupt inputs and dedicated I/O modules. For OEM applications we can offer attractive customized solutions. Interrupt inputs on PCD2.M120 , PCD2.M150 , PCD2.M170 , PCD4.M170 (1kHz unidirectional max.) Counter modules PCD2.H100 (simple, 20kHz max.), PCD2.H110 (versatile, 100kHz max.), PCD4.H120 (versatile, 166kHz max.)

supply voltage pins 1L/2L and 3N/4N are inverted. This wrong label is present on the schema of the housing and directly on the pins. Problem When a PCD7.T162 produced before week 22 of 2011 (30.05.2011) has a 24V DC supply voltage it does not work when it is connected like described in the schema on the housing. Solution The pins 1L/2L and 3N/4N are printed inversely. This means that the functionality is still the same but the 24V DC need to be connected to the pins 3N/4N and the 0V to 1L/2L. Remark Units of PCD7.T162 produced after 11/22 (30.05.2011) are correctly labelled and

a PCD2.M5xx0? (FAQ #101386) No, the PCD4.C225 is not supported by a PCD2.M5xx0 CPU. Due to the higher processing speed of the PCD2.M5 (compared to e.g. a PCD2.M150) it can not be guaranteed that the I/O modules are correctly accessed. Why is this fact not stated in the manual for the PCD4? In the manual for the PCD4 (27/734) there is not information regarding this restriction (it is only stated that a PCD2.M110 can not be used togheter with the PCD4.C225, and that no H-Modules or W1/W2/W3 modules
