11 INSTRUCTIONS AND FUNCTIONS
• <event number> is used as a number for specifying whether enabling or disabling the
defined event to occur, for creating an event, and for waiting for an event to occur. Treat
<event number> as the common number between the BASIC programs.
A value ranging 0 to 63 can be specified to <event number>, and <event number> is
shared with the event by the communication module's expansion relay (EM).
• If an event number that has been already defined is specified, the contents of the previous
definition become invalid and the newly defined contents become valid.
Defining an event by the communication module's expansion relay (EM)
• Defines an event that is generated when the communication module's expansion relay
(EM) changes from OFF
number>.
• The event defined by this method is generated by the ZSIGNAL instruction and by the
change of the target bit device (OFF
a program is waiting for the event to occur by the ZSIGNAL instruction or by a change of
the target bit device, after enabling the event to occur by the ZEVENT instruction.
• <event number> is used as a number for specifying whether enabling or disabling the
defined event to occur, for creating an event, and for waiting for an event to occur. Treat
<event number> as the common number between the BASIC programs.
A value ranging 0 to 15 can be specified to <event number>, and <event number> is
shared with the event for synchronization between the programs.
Only 0 to 15 can be specified for the event number of an event from the communication
module's expansion relay (EM). An error occurs if 16 to 63 is specified.
• Specify the communication module's expansion relay (EM), which generates the defined
