The following program example is relevant for Special I/O Units mounted to the
CPU Rack or Expansion I/O Racks only, because END refreshing is always per-
formed on Special I/O Units mounted to Slave Racks regardless of the PC Setup
settings.

Note IR 30000 is used in an OUT instruction twice in this program. Although accept-

able in the above example, this type of duplication is not usually allowed unless
there is a specific reason and then only when proper operation can be ensured.

An Analog Timer Unit’s timer SV can be changed easily without a Programming
Console. The Unit is equipped with an external variable resistor connector, so a
variable resistor can be installed in the control panel and connected to the Ana-
log Timer Unit to set or adjust the timer SV manually.

When the Timer Start Input is turned ON, the Timer Set Bits allocated to the Ana-
log Timer Unit (bits 00 to 03 of n) are turned ON, the analog timer begins to oper-
ate, and the timer set indicator (SET) on the Unit will light.

When the Unit’s timer SV (set internally or externally) elapses, the Unit’s Com-
pletion Flags (bits 08 to 11 of n) and the Time-up Output will be turned ON. Also,
the time-up indicator on the Unit (TIME UP) will light.
