5.2 Address Map and Display Symbols
The address map and the relationship with external devices is shown below.
(1) Addresses of Input Signals from the Machine (#1000 to #1063)
For the signals input from the machine operation panel and electric control panel, such as
those of push-button switches and limit switches, addresses #1000 to #1063 are assigned.
The correspondence between the address and the input signal should be determined by the
machine tool builder.
• One bit of address (#1000 to #1063) corresponds to one point of input signals.
Address number and bit number are determined depending on the pin number and the
connector number of the I/O board where the input signal is connected.
Example:
• The input signals of #1000 to #1063 are expressed by the following symbols.
