(1) Applicable CPU
· A1SCPU(S1)
· A1SJCPU(S3)
· A1SJHCPU(S8) · A1SHCPU
· Q2ASCPU(S1)
· Q2ASHCPU(S1) · A1SCPU24-R2
(2) Number of modules loaded
As long as the number of I/O points for the applicable CPU is not exceeded,
there is no limit in the number of modules used.
(3) Slots for loading
The module may be loaded into any of the base module slots, expect the
following:
If the module is loaded in a slot on an extension base module that is not
equipped with a power supply module (A1S52B, A1S55B or A1S58B), the power
capacity may be insufficient to cover all the modules.
When loading to an A1S66ADA extension base module without a power supply
module, select a proper power supply module, basic base module, extension
base module and extension cable by taking the following points into
consideration:
1) Current capacity of the power supply module on the basic base module
2) Voltage drops of the basic base module
3) Voltage drops of the extension base module
4) Voltage drops in the extension cable
(4) Data link system
In a data link system, the module may be loaded to the master station, local
station or remote I/O station. Refer to the MELSECNET or MELSECNET/B Data
Link System Reference Manual for program examples for remote I/O stations.
Remark
Refer to the respective manual listed below for calculation methods for the range of
I/O points and voltage drops. This shows the system configuration when using the
graphics software to create monitor screens.
