Chapter 7 Application Examples
Figure 26 shows the Input Configuration tab of the ArmorBlock Module
Properties. In this example, Points 0 and 1 monitor the OSSD outputs of the
safety switch. The Type must be set to Equivalent, and Mode must be set to
Safety. Points 4 and 5 monitor the status of the output contactors K1 and K2.
The Type should be set to Equivalent. The discrepancy time will be dependent
on the contactor device — a value other than 30 may be needed. Safety pulse
testing is used to detect potential faults in the monitoring circuit.

Figure 27 shows the Test Output tab of the ArmorBlock Module Properties.
In this example, Points 0 and 1 are set to Standard. This allows these points to
be controlled by the program. Point 0 applies power to the 440G-LZ. By
setting it to standard, the user can programmatically turn this point off and on
if the 440G-LZ switch has a fault condition. Point 1 is the lock/unlock
command. In this example, the 440G-LZ is a PTR type, so 24V unlocks the
switch. Points 4 and 5 are used to monitor the contactor outputs and are set to
Pulse Test.

Figure 28 shows the Output Configuration tab of the ArmorBlock Module
Properties. Points 0 and 1 drive the output contactors K1 and K2. The point
Types are set to Dual, and the Modes are set to Safety.
