The following ladder program will be used to demonstrate how to write a pro-
gram with the Programming Console. This program makes output IR 01000
flicker ON/OFF (one second ON, one second OFF) ten times after input
IR 00000 is turned ON.
The mnemonic list for the example program is shown in the following table.
The steps required to enter this program from a Programming Console are
