Explanation
• Area type specification (word m)
Specifies the memory area of PLC to which the custom bit area is allocat-
ed.
00: Does not use the custom bit area
01: CIO area
Specifies CIO area of PLC starting from the specified first address
(m+1)
02: WR area
Specifies WR area of PLC starting from the specified first address
(m+1)
When mounting several MC Units on the same PLC, make sure that the oper-
ation data areas of the MC Units do not overlap. Since MC Units do not detect
the error even if custom bit areas of different Units are overlapping in PLC, a
malfunction may result.
• First address (word m+1)
When either CIO (0001) or WR (0002) area is specified for the custom bit
area in the area type specification (word m), the first address is to be spec-
ified.
Set the first address in hexadecimal (Hex). The setting ranges are as fol-
lows:
CIO area: 0000 to 17BB Hex (0 to 6075)
WR area: 0000 to 01BB Hex (0 to 443)
When "Does not use the custom bit area (0000)" is specified in area type
specification (word m), this setting is not necessary.
