If the C200H Slave Rack is connected to another SYSMAC model Remote I/O
Master Unit, such as the C500, C1000H, or C2000H, it is not possible to use a
Special I/O Unit with the C200H Slave Rack.
WARNING
Always turn the PC power OFF before connecting or disconnecting a Unit,
terminal block, or output connector.
Caution
Connect thermocouples with the appropriate compensating conductor.
Wire I/O leads in separate ducts from power leads to prevent noise problems.
Units with the following lot number or later support the following new functions.

Descriptions of New Functions
RUN/STOP Bits
Stop Bits have been added. These bits are supported with either fixed or normal
memory allocations.
Word (n+2), bit 06
Loop 1 Stop Bit
Turn OFF to perform
temperature control for the
Word (n+2), bit 04
Loop 2 Stop Bit
tem erature control for the
loop. Turn ON to stop
control.
Note These bits cannot be used when SW203-5 is set to ON to stop control in PRO-
GRAM mode. When SW203-5 is ON, control is always stopped.
Unit status will be as shown in the following table depending on the combination
of SW203-5 settings and operating mode of the CPU Unit.

•
To run or stop the temperature control using the Stop Bits, set SW203-5 to
OFF.
•
To run or stop the temperature control only through the operating mode of the
CPU Unit, keep the Stop Bit OFF (RUN).
RUN/STOP Monitor Flags
Stop Flags have been added. These flags are supported with either fixed or nor-
mal memory allocations.
Word (n+8), bit 08
Loop 1 Stop Flag
When OFF, temperature
control is being performed
for the loop When ON
Word (n+9), bit 08
Loop 2 Stop Flag
for the loop. When ON,
control is not being
performed.
These Flags turn ON and OFF depending on whether temperature control is run
or stopped. Therefore, they do not necessarily have the same status as the Stop
Bits described above.
RAM Write Commands
Previously, commands could be used to read and write to the EEPROM only.
These new commands allow writing to RAM.
