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 pro­tective 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:

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.

The extensions PCD2.C1000 or PCD2.C2000 can be chained up to address 1023
(including the 64 addresses available in the PCD itself. That means 64 I/O mod­ules can be connected to the system.

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 memo­ry. 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.

10.3.2.3 Counter Mode Description

The Counter Mode is confugured in the IO-Conguration (On Board IO’s Inputs /

Interrupts / Counter / Watchdog )

X1 Encoding

In this mode, the counter is set on every positive edge of A and counts up or down
depending on the B state.

X2 Encoding

The same behavior holds for X2 encoding except the counter increments or decre­ments on each edge of channel A, depending on which channel leads the other.
Each cycle results in two increments or decrements, as shown in Figure.

X4 Encoding

The counter increments or decrements similarly on each edge of channels A and
B for X4 encoding. Whether the counter increments or decrements depends on
which channel leads the other. Each cycle results in four increments or decre­ments, as shown in Figure.

11 Watchdog relay

PCD2.M4_ CPUs have a hardware watchdog as standard equipment. The watch­dog relay is at Pins 5 and 6 at Plug X4.

Technical data

Number of outputs 1× relay switching contact
Function Watchdog function or user output (selectable)
Max. voltage 48VAC or VDC
Switching capacity 1A (with DC switch-on voltage, a freewheeling diode should be con-

nected in parallel to the load)

Functional description

As soon as the watchdog relay is called at the address O 255 by a switch on/

o󰀨 frequency of < 200ms (or other value congured in device congurator), the
relay contact closes. It remains closed until the pulse time exceeds the congured

value.

Example of an instruction list (IL) sequence:

Label Command Operand Comment

COB 0 ; or 1 … 15

0

STL WD_Flag ; invert the help ag

OUT WD_Flag

OUT O 255 ; Output 255 blinking

ECOB

With this code the watchdog triggers even for (continuous) loops that are due to
programming. Regarding user program cycle time, please note the following:

With cycle times longer than 200 ms, the code sequence must be repeated
multiple times in the user program in order to prevent the watchdog triggering
during RUN.

In manuals, this symbol refers the reader to further information in this manual or other
manuals or technical information documents. As a rule there is no direct link to such
documents.

This symbol warns the reader of the risk to components from electrostatic discharges
caused by touch.

Recommendation: Before coming into contact with electrical components, you should
at least touch the system’s negative pole (cabinet of PGU connector). However, it
is better to use a grounding wrist strap with its cable permanently attached to the
system’s negative pole.

This sign accompanies instructions that must always be followed.
