Removing the cover exposes components that are sensitive to electrostatic discharges.
Recommendations:
Immediately before touching the electronic circuits, briefly touch the
metal housing of the PGU connection. It is safer to use an anti-static wrist band, connected
to the Minus of the system.
I/O modules and I/O terminal blocks may only be plugged in and removed when the
Saia PCD
®
and the ex24 V are disconnected from the power supply.
Removing the cover exposes components that are sensitive to electrostatic discharges.
3.4.3 Hardware and firmware versions for the PCD1
The firmware versions for the PCD1.M1xx are generally upwardly compatible in terms
of hardware, so old CPUs can be fitted with new firmware, in order to take advantage
of new functions. This feature is highly valued, and we will try to retain it for as long
as possible; however, we cannot guarantee this.
At this point, the following known restrictions apply:
● The use of intelligent communication modules such as Profibus DP, LON and Eth
-
ernet requires the minimum hardware and firmware versions. Please refer to the
manuals for the relevant communication modules
