MELSEC-A
(8)
Max. 8 k/14 k steps of program
An AnSCPU allows the creation of a program of up to 8 k (A1SCPU(S1)/
A1SCPUC24-R2)/ 14 k (A2SCPU(S1)) steps containing up to 26 sequence
instructions, 131 basic instructions, 106 application instructions, and 8 CC-
Link dedicated instructions.
In addition, microcomputer programs and utility programs created by the user
can be used.
(9)
SFC language compatible
An AnSCPU contains a microcomputer program area, so it can use an SFC
program by using the software on an IBM personal computer.
(10) Two extension connectors, on the right and left sides.
(A1SJHCPU(S8) on the right side only)
In order to facilitate wiring wherever the extension base unit is installed,
extension connectors are provided at both left and right sides of the
AnSHCPU and extension cables that suit the requirements imposed by
different mounting locations are available.
(11) Use either screws or DIN rail for panel installations
The AnS base unit is provided both with screw holes and, on its rear face, the
fixture for mounting it to a DIN rail.
(12) Easy-to-see terminal block symbol sheet
•
A terminal block symbol sheet is attached to the front of AnS I/O modules.
It is possible to write I/O device numbers, connector numbers, etc. on one
side of the sheet.
•
Terminal symbols for 16 I/O signals can be written on the other side.
(13) A[ ]N, A[ ]A-series I/O module and special function module compatible
By connecting an A[ ]N, A[ ]A-series extension base unit, A[ ]N, A[ ]A I/O
modules or special function modules can be used.
(14) Same programming environment as other MELSEC-A CPU modules
A sequence program can be created using the peripheral device currently
used for other MELSEC-A CPU modules.
For details on the applicable peripheral devices, see Section 2.2 "Cautions on
System Configuration".
