For "reading" a value from a PCD text (e.g. copying "1234" from a PCD text with content "The next number is: 1234" into a Register) a new System Function has been added for PCD3 and PCD2.M5xx0.
In the system catalogue there is a schematic of a PCD connected to a BACnet/IP network which could lead to a missinterpretation. Although BACnet is supported by a PCD3 or a PCD2.M5xx0 and LON on IP will be suppored in future, it won't be possible to run both stacks on the same PCD at the same time.
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.
No, the GSD-Files are different. They have a different identification. The PCD2.M170 needs the GSD-File PCD2_Slave (SAIAcd20.gsd), otherwise the PCD4.M170 needs the PCD4.M170_Slave (SAIAcd40.gsd)
The PCD2.H322 and PCD2.H327 are slave modules. Nonetheless the second axis can be used as master.
With the PCD7.R610 memory it is necessary to use a new firmware version 1.23.32 or newer. The firmware 1.23.32 does require a recent hardware version of the PCD with extended memory size. Attention: If the FW 1.23.32 is loaded to a not compliant hardware version then the firmware download is interrupted at about 86% with a NAK response message. In this case it's only possible to re-load the FW 1.22.xx to the PCD. Since PG5 2.1.311 the firmware downloader does verify the hardware version of the connected PCD and prevent the loading of a FW 1.23.xx to a not compatible PCD.
Yes. With all xx7 series PCD2 controllers, the operating system can be updated via a serial port. PCD3 systems can be updated using the USB port.
space Communication interfaces are directly mounted onto the main print of a CPU and therefore do not require additional space. A PCD2.M480 may handle up to 8 serial interfaces [...] Server Newer classic PCD types (introduced after 2000, e.g. PCD2.M170, PCD2.M480, PCD3.Mxxxx, PCS1) do have an integrated Web Server (no extra costs) in the Firmware (FW). To access the Web server the software Web Connect is needed and to generate project containing a PCD internal Web server the Web Builder is required. Both tools are part of the Controls Suite. S-Bus as communication
. 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
