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.
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.
The PCD2.H322 and PCD2.H327 are slave modules. Nonetheless the second axis can be used as master.
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)
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.
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.
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.
Yes, a new set of instructions for calculation with IEEE floating point values (single and double) has been added to the firmware of PCD2.M480, PCD2.M5xx0 and PCD3.
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
