words
Explanation
• No. of transferred words (word m+4 bit00 to 07)
Specifies the No, of words transferred between CPU Unit and MC Unit.
The No. of words specified here starting from the first address specified in
(word m+5) is transferred.
• Area type specification (word m+4 bit08 to 14)
Specifies the memory area of PLC to which the general I/O area is allocat-
ed.
00: Does not use the general I/O area
01: CIO area
Specifies CIO area of PLC starting from the specified first address
(m+5).
02: WR area
Specifies WR area of PLC starting from the specified first address
(m+5).
03: DM area (custom address)
Specifies DM area of PLC starting from the specified first address
(m+5).
04: EM area (custom word)
Specifies EM area of PLC starting from the specified first address
(m+5).
• PORT direction (word m+4 bit15)
Specifies the direction of transferring general I/O.
0: MC Unit _ CPU Unit
Output variables of MC unit (with PORT_A: from OW0B00 on) for the
specified No. of transferred words (word m+4 bit00 to 07) are trans-
ferred to the memory area of PLC specified with the area type specifi-
cation (word m+4 bit08 to 14) and the first address (word m+5).
1: CPU Unit _ MC Unit
The specified No. of words (word m+4 bit00 to 07) is transferred from
the memory area of PLC specified in the area type specification (word
m+4 bit08 to 14) and the first address (word m+5) to input variables of
MC Unit (with PORT_A: from IW0B00 on).
When EM area (04) is specified for the operation data area in the area type
specification (word m+4 bit08 to 14), EM area is fixed at Bank No.0.
Do not set the bank No. of the file memory on PLC. Specifying EM area of the
file memory bank No. causes the alarm [0044h: CPU memory error].
When mounting several MC Units on the same PLC, make sure that operation
data areas do not overlap. Since MC Units do not detect the error even if gen-
eral I/O areas of different Units are overlapping in PLC, a malfunction may
result.
