This is a new series of articles on various topics using Schmersal’s PSC1-C-100-FB1 Safety Controller.Episode 2 is connected to emergency stop and creating a safety program.

Come on, let’s enjoy FA.

Implementation

In this article, the flow is as follows: add each connection input/output component > create safety program > download project.

Add ESTOP

In the previous article, we introduced the basic operation of the Schmersal SafetyPLC2 tool, project creation, etc.We will continue with the previous article by opening the Terminal Scheme Tab>Library>Input>Emergency Stop and adding it to the project.

Done!The emergency stop has been added, but the part itself is still red, so either there is a configuration error or it is not being used within the safety program.

You will also see the emergency stop component you just added in Project>Peripherals>Input.

Configure

Now we can set parameters for emergency stop components.

Parameters for the appropriate part can be set from the Properties screen.

Type

This sets the wiring type of the emergency stop.

Let’s set it to 2.NC this time.

Change IO Signal

You can set the IO pins that you plan to wire to the corresponding component in the Signal #1 item.

Emergency Stop

Such a switch type can be configured for emergency stop components.

Type	Design
1 (1 N.C.)	B contact x1
2 (2 N.C.)	B contact x2
3 (2 N.C. TimeMonitored)	B contact x2 + time monitoring

Add Safetey Output

Next, from the Terminal Scheme Tab, add the Output>PN Semicondutor Safety Output component to add the safety output component.

Configure

Set the parameters of the safety output from the Properties screen.In this article, we will set the Output Type to “Standard”.

The safety output component you just added appears in Project>Peripherals>Output.

PN semiconductor output

PN半導体出力にはこのような設定が可能です。

Type	Design
Standard	“HISIDE” (=P switching) or “LOSIDE” (=N switching) can be selected as standard output.Can be selected as a standard output (depends on the output used).The use of standard outputs alone is not suitable for safety reasons.
Redundant	This option forces a combination of “HISIDE” (=P switching) and “LOSIDE” (=N switching) outputs.

Add Reset Button

The final step is to add a Confirm Button component from the Input Library.

Done!

Configure

Configure the part in Properties.For this fall, just set Type to NO.

Confirm Button

The Confirm Button can be set to this type of switch type.

Type	Design
1 (1 N.O.)	A contact x1
2 (1 N.C.)	B contact x1
3 (2 N.C.)	B contact x2

Program

Here is the safety program we created for this article.

When the Emergency Stop is turned OFF, it fires the Reset input of the FILP FLOP > Resets the FILP output
When the emergency stop is turned on, it passes through delay Timer1, and when the Confirm Button is pressed again, it fires the SET input of the FILP FLOP > sets the FILP output
FILP FLOP output is reflected in the output PN Semiconductor just added
