It is absolutely necessary to enable the motor driver after the initialisation of an H3xx. Otherwise the motor will move unintendedly and uncontrolled.
Due to a hardware problem the flash memory modules PCD3.R5xx produced before August 2006 may not be used in the I/O slot 3 of the PCD3 hardware version B.
If the "Electric Heat" output K 1/2 of the PCD7.L60x room controllers is written to 100% in RIO mode, it is still switched off after around 15 minutes for 2 minutes.
The PCD2.H322 and PCD2.H327 are slave modules. Nonetheless the second axis can be used as master.
The RS-232 S-Bus communication may doesn't work at all with PCD2.F2xx0 or PCD3.F2xx modules when communicating over converters (like modem or optical converters) to other devices. On PCD2.F2xx0 and PC
The reason for this behaviour of a PCD7.L6xx is often related to the window contact which is not closed.
If a Restart Cold is performed but the power supply wasn't interrupted, it is possible that the PCD4.H120 won't work correctly and it is even possible that the FB's provided to run the H120 will hang
No this modul is not supportet on the xx7 CPUs. PCD7.R550 is supported (4 MBytes data connection over FTP). PCD7.R500 is supported (User program backup).
On the back side of the module you find a stamp which such a code, for example: 51R 2.2. The meaning is 51st week of 2003 firmeware version 2.2. See below the year code:
