PLC External Interface option
The PLC external interface option allows remotely located contact closures to select one of seven
sets of pre-programmed test parameters. The test parameters are entered in memory sets M1~M7.
Operation of the PLC remote interface does not require a true PLC, as simple switch closures are
effective at selecting, starting and stopping stored test programs. However, although simple
switches can be used, they require manual operation. The use of a PLC permits external
automatic control of the test programs in memories M1~M7.
The proper connections for the PLC external interface are shown below.
Signal Input (Option)
OUTPUT ON/OFF
Connect between PIN 3 and PIN5
Memories Input Control can be achieved by using Normally Open (N.O) Momentary Switches
and the connections as shown in the table above.
For an example,
Memory 3 (M3) Connect PIN 8 and PIN 9 with a series diode (ex. 1N4148) at each pin and the
common point is connected to PIN 5.
The procedure for storing parameters in memories M1~M7 is explained in Program Memory
Procedures (Programming) chapter 4 page 4-14.
