4. Enter the relay number.
1 The mnemonic for a parallel connection, a comma and a period (, .), can be used at step 3. to display a
parallel connection.
2 Once step 4. has been completed, the input position for the next instruction will be to the right of the
parallel connection.
„ Creating a Pulse Generation Circuit
Pulse Generation Circuits are programmed the same way as the branching method explained
in the three preceding sections, Setting Branches, Settings Connection Points, and Setting
Parallel Connections.
The procedure to create the pulse generation circuit shown in the above diagram is outlined
below.
1. Enter the N.C. CONTACT instruction.
2. Select the ON PULSE instruction and then enter the branch.
3. Enter the register number which is the operand for the ON PULSE instruction.
4. Enter the COIL instruction.
