type
(1) Execution type
*1
Specify whether to use the parameter value set by the engineering tool or the value
set in (s2)+4 to (s2)+14 of control data for opening a connection.
• 0: Performs open processing according to the "external device connection
configuration" set by the engineering tool.
• 1: Performs open processing according to the setting in (s2)+4 to (s2)+14 of
control data.
If the CP.CONOPEN instruction is executed by setting the value for the external
device connection configuration of the engineering tool and also setting device
(s2)+0 to 1, the instruction performs open processing according to the value set in
its control data.
Even if a value is set in (s2)+4 and later after setting (s2)+0 to 0, the value is
ignored.
