It sets up or indicates the I/O assignment of S-LINK system.
Immediately after power supply or reset of computer, it indicates the setup condition of the I/O
setting switches (I/O SET0 to 3) of “3) Mode switch” of “3. Functional Description.”
When setting is done by a program, I/Os can be set in units of 16. Set all I/O setting switches to
input (“0”: ON) to write in.
bit Assignment
7S-LINK address 112 to 127 I/O setup (0: Input, 1: Output)
6S-LINK address 96 to 111 I/O setup (0: Input, 1: Output)
5S-LINK address 80 to 95 I/O setup (0: Input, 1: Output)
4S-LINK address 64 to 79 I/O setup (0: Input, 1: Output)
3S-LINK address 48 to 63 I/O setup (0: Input, 1: Output)
2S-LINK address 32 to 47 I/O setup (0: Input, 1: Output)
1S-LINK address 16 to 31 I/O setup (0: Input, 1: Output)
0S-LINK address 0 to 15 I/O setup (0: Input, 1: Output)
It is used for bank change-over of “.”
First, write in the number (“00” to “03”) into “”
from the computer. Then, 1.4 to 21.4 ms later, control board changes over bank of “
,” and writes in the changed bank number into “-
sponse register.”
Notes: 1) In case a number other than “00 to 03” is written into “
register,” it compulsorily changes over bank to “00.”
2) Do not read out / write in “” until “
response register” has been changed over.
It has the same operation as bit 6 of “,” system set.
When a number other than “00” is written, the S-LINK system connection condition at that time is
read.
It becomes “00” after reading.
It has the same operation as bit 7 of “
completion.
In case of sending different outputs to the same address, the former output data will be ignored
if the next output data is written in before the former output data has been transmitted to the
S-LINK
the output data has been transmitted to the S-LINK output unit.
When writing in a number other than “00” after writing in output data, it automatically becomes “00”
after the output data is transmitted to the S-LINK output unit. So, transmission error of output
the program.
