Program
example
• The available setting areas for the P Type(Optical) Link System are :
LINK = 0001(H1) to 0011(H3)
Station number(UNIT NO.) = 00000001(H01) to 00111111(H3F)
For ditails about the P Type(Optical) Link System, refer to the P Type(Optical) Link
System Technical Manual.
• When the flag R9031(special internal relay) turns ON(1), one of the following error
codes are stored in DT9039(special data register).
71(Hexadecimal)
: Response signal incicating that the transfer operation cannot
be received.
72(Hexadecimal)
: Buffer for the link is full.
73(Hexadecimal)
: A response message was not received.
When one of above mentioned errors occurs, check the value of the time-out in
system register number 32. The time out value can be set in the range of 10ms to
81.9s(default = 2s)
