Zones - Omron CS1W-MCH71 Operation Manual

Zones

9-7 Zones
Overview
Using Zones
Zones are supported for MC Units with unit version 3.0 or later.
A zone bit turns ON when a specified variable is within the set range, and turns OFF
when the variable is outside of the range.
A maximum of 32 zone bits can be set.
Perform the following operations to use zones.
• Set the following system parameters:
(1) Set the number of zone bits to be used.
(2) Set the leading address of the area where the zone upper and lower
limits are to be set.
(3) Set the variable types and addresses of the variables that are to be
monitored.
(4) Set the output variable addresses and bit numbers for where the mon-
itoring results (ON/OFF) are to be output.
• Set the zone upper and lower limits from the motion program or the CPU
Unit.
• Enable or disable the zone bits from the motion program or the CPU Unit.
■ Setting System Parameters
As shown in the following diagram, set the two Unit parameters and the two
zone parameters for each axis.
(2) Zone data leading address
(P00012)
(1) Number of zone bits
(P00011)
■ Setting Upper and Lower Limits for Zone Bits
Set the upper and lower limits for each zone bit from the address specified in
P00012.
To make the setting from a motion program, substitute the upper and lower
limits for this address.
If the position data area is specified in P00012, the setting can also be made
using the Support Tool. In this case, the zone bit upper and lower limits can be
saved in flash memory.
To make the setting from the CPU Unit, allocate this area as a general-pur-
pose I/O area or use the IOWR instruction.
(3) Zone bit reference value address
(P6ZZ01)
Zone bit 1 lower limit
Zone bit 1 upper limit
Zone bit 2 lower limit
Zone bit 2 upper limit

(4) Zone bit output address (P6ZZ02)
Zone bit 32 lower limit
Zone bit 32 upper limit
