transferred with the ladder program must be set with the Programming
Console.

Set the IR area allocated to the High-speed Counter Unit to commands
that are used for the operation of the High-speed Counter Unit.
6.
Use the commands sent from the PC to the High-speed Counter Unit and
the status data of the High-speed Counter Unit to write programs for sys-
tem control.
Set the MACHINE No. switch within a range of 0 to F.
Set the MODE switch within a range of 0 to 6 for the following modes.
0: Simple counter mode

Note
Refer to
2-2 High-speed Counter Unit Components
for the settings of
MACHINE No., MODE, and rear setting switch.
A data area of the PC can be set to a range and to count value data with a
ladder program or the Programming Console. The data can be transferred to
the High-speed Counter Unit even if it is in operation.
Data can be transferred by setting data transfer bit to 1. When the C200HX,
C200HG, or C200HE PC is used, the IOWR instruction can be used to
change ranges and count values.
