Setting data Description
(S1) Vision system (camera) No. to log on (1 to 32)
(S2) Timeout until vision system logon is completed (1 to 32767) [10ms]
Processing details
• The vision system specified with (S1) is logged on.
• The Motion SFC program execution transits to the next block without waiting for the completion on the vision system logon.
After process completion, the status storage device value set in the Ethernet communication line setting parameter is 20
(reception enable).
• (S2) is set in increments of 10ms. When the setting is omitted, the timeout time is 10 seconds (same as setting 1000).
Operation error
An operation error will occur if:
• The (S1) data is outside the range of 1 to 32.
• The (S2) data is outside the range of 1 to 32767.
• MVOPEN is executed again for the vision system that has been logged on.
• The vision system parameter setting is different from the setting on the vision system.
• The logon is not completed when the specified timeout time has elapsed.
