YASNAC PCNC PLC Programming Manual Chapter 5: Address Numbers And Map
(2) Addresses of Output Signals to the Machine (#1100 to #1163)
For the signals output to the machine operation panel and electric control panel, such as the
signals of lamps and solenoids, addresses #1100 to #1163 are assigned. The correspondence
between the address and the output signal should be determined by the machine tool builder.
• One bit of address (#1100 to #1163) corresponds to one point of output signals.
Address number and bit number are determined depending on the pin number and the
connector number of the I/O board where the output signal is connected.
Example:
• The output signals of #1100 to #1163 are expressed by the following symbols.
(3) Addresses of Input Signals from the NC’s Main Section (#3500 to #3799)
For the signals input from the NC main section, in other words, the signals output from the
NC main section to the PLC, such as M-BCD signal, addresses #3500 to #3799 are assigned.
The correspondence between the signal name and the address is determined by the NC and
cannot be changed.
• One bit of address (#3500 to #3799) corresponds to one point of input signals.
Example:
• The input signals of #3500 to #3799 are expressed by the following symbols.
