Note 1. PID Units, Magnetic Card Reader Units, Fuzzy Logic Units, and Cam Posi-
tion Units cannot be mounted to Slave Racks in SYSMAC BUS/2 Systems.
2. The PID Unit and some Position Control Units require two slots on a Rack.
3. The Personal Computer Unit requires four slots on a Rack.
4. Although no words are allocated to the Remote I/O Master and Slave Units
themselves, words are allocated to Units mounted to Slave Racks or other-
wise connected to the Remote I/O System. Refer to 3-3-3 SYSMAC BUS/2
Area and 3-3-8 SYSMAC BUS Area, for details.
5. 3G2A5-LK010-E I/O Link Units and C500-ETL01 Teaching Tool cannot be
set to 16 point input/16 point output on a CVM1, CVM1D, or CV-series PC.
6. The I/O READ and I/O WRITE instructions (READ(190)/WRIT(191)) can be
used for Units mounted to Slave Racks in SYSMAC BUS/2 Systems (but not
in SYSMAC BUS Systems) under the following conditions.
a) The lot number of the Remote I/O Master Unit and Remote I/O Slave Unit
must be the same as or latter than the following.
1992
October (Y: November; Z: December)
1st
01 X 2
b) The DIP switch on the Remote I/O Slave Unit must be set to “54MH.”
c) The Special I/O Unit must be one of the following: AD101, CT012,
CT041, ASC04, IDS01-V1, IDS02, IDS21, IDS22, LDP01-V1, or NC222.
7. Refer to the CVM1D Installation Guide or to the operation manuals for indi-
vidual Units for specific mounting procedures and limitations.
8. Interrupt Input Units operate as normal 16-pt Input Units.
Once the word(s) assigned to a Unit has been determined, the use of individual
bits in the word(s) is determined by the type of Unit. If the Unit is a Special I/O
Unit, I/O Link Unit, or CPU Bus Unit, each bit will have a dedicated function. Re-
fer to the Operation Manuals for the relevant Units for details.
With I/O Units, bits within a word are assigned to terminals starting at the top of
the I/O Unit with bit 00 and going sequentially to the bottom. If the first Unit on the
left of the CPU Rack is an Input Unit, the top terminals (i.e., the top input point)
will be assigned CIO 000000, the next terminals, CIO 000001, and so forth for
all of the terminals on the Unit. The allocation order is illustrated below. Arrows
indicate the order in which words are allocated to Units for the rack number set-
tings indicated.
