'*+ ,&7 & 879
This is an area to read out input data and write in output data of
S-LINK
units.
In case of input, “0: Input OFF” or “1: Input ON” is read out in each bit.
In case of output, write in “0: Output OFF” or “1: Output ON” in each bit.
Notes: 1) Output is saved until you overwrite with the next output data.
2) In case output data is written into a unit address which has been set as an input, the written data is
ignored and new input data is set after 1.4 to 10.7ms.
'*+ ,&7 & 8
Control board product information (version number, etc.) is registered in ASCII code.
'*+ ,&7 & #8
It shows the addresses of
S-LINK
units at which ER4 has occurred.
When a bit is “1,” ER4 (cable disconnection or abnormal
S-LINK
I/O unit) has occurred at the
S-LINK
unit having that address.
Note: Addresses of units where ER4 occurs is held on. ER4 can be released (“0”) by switching on again either
the
S-LINK
system side power supply (+24V DC) or the PC/104 bus side power supply (computer
' + +
'*+ ,&7 & 8
It shows the addresses of the
S-LINK
units connected on the
S-LINK
system main cable.
When a bit is “1,” an
S-LINK
unit is connected at that address.
Note: When an
S-LINK
}^` \ 9
address of that unit is set to “1.”
