2.1 Prerequisites
The PCD2.M4x60 must be used with the PG5 Suite v2.2.050 or higher.
2.2 Instructions for connecting Saia PCD®controllers to the internet
When Saia PCD controllers are connected directly to the internet, they are
also a potential target of cyber attacks. For secure operation, appropriate pro-
tective measures must always be taken.
PCD controllers include simple, built-in protection features. However, secure
operation on the internet is only ensured if external routers are used with a
rewall and encrypted VPN connections.
For more information, please refer to our support site:
www.sbc-support.com/security

A push button is placed near the USB connector (X1).
The operating mode can be changed during operation or during power-up.
If the button is pressed in Run mode for longer than ½ second and less than
3 seconds, the controller switches to Stop mode and vice versa.
If the button is pressed for longer than 3 seconds, the last saved user program is
loaded from the ash memory.

9 Data retention, Real time clock and battery module slot
9.1 Usage of optional battery module
The slot for the PCD3 battery module will be unused for the most of applications.
This option will be used only for customers they need to keep the real time clock
up to date when the system stays unpowered more than 10 days.
For an unpowered duration up to 10 days, the real time clock stays alive by a
super-capacitor.
9.2 User program data
The user program medias (registers, ags, etc.) are stored in a non-volatile memo-
ry. That means the information is not lost when the system is unpowered and even
if the system has no battery module plugged.

10 Digital interruptive inputs
Digital inputs respecting standard IEC 61131-2:
Voltage input lower than 5V is considered as state “low” and voltage higher than
15V is considered as state “high”.
Maximum input voltage = 30V.
10.1 Usage in normal digital inputs
To use the digital inputs as normal inputs, choose the mode “Input” in the device
congurator.
10.2 Interruptive inputs
To use the digital inputs as interruptive inputs, choose the mode “Interrupt”. The
interrupts can be triggered on rising edge, falling edge or both.
A XOB is called when an interrupt is detected. The XOB number is congured by
default at XOB 20 for input 0 up to XOB23 for Input 3.

10.3 Onboard Counter
10.3.1 Introduction
The four Interrupt Inputs can be used as two independent On board Counters.
This On board Counter is counting independent of the CPU Cycle.
On the PCD1.M22_ the Onboard Interrupts and the Onboard Counter are using the same
Inputs. These Functions can’t be used in parallel.
The onboard Counter is able to count bidirectional.
The Overow handling is congurable. If a congurable reference Value is
reached, it is possible to call a Process Alarm XOB.
The max counter Frequency is limited to 1 kHz.

10.3.2.2 Function Description
To congure, to start and stop the Onboard Counter there exist a system call
(BOARDCNT). For the conguration and to start the Counter only a single call of
the system call is necessary. The Counter value can be read with a direct periph-
ery access on address 65’000 / 65004. The Value of the Counter can be set at any
time with a direct periphery write access to address 65’000 (Counter 0) or 65004
(Counter1).
●On a startup, the Counter is preset to 0.
●If the PCD goes to halt the counter is stopped.
●To change the Counter Parameter, the counter must be stopped.
ROTATE: In the Rotate Mode the counter counts up to the Reference Value
(Parameter Ref) and starts then from 0. Or it counts down to 0 and starts with the
Reference Value. In “normal” Mode theCountingRangeis from 0 to 0xFFFF'FFFF.
