(17) Cam data/limit switch output data batch-change completion flag (M2057)
................................................................................. Signal from PCPU to SCPU
(a) This flag is used to confirm normal completion of cam data/limit switch
output data changes.
1) The flag turns ON at normal completion of cam data/limit switch output
data changes.
2) Turning M2056 OFF also turns M2057 OFF.
(b) While cam data/limit switch output data are being imported, the real mode
cannot be switched to the virtual mode.
Use M2056 as an interlock for switching to the virtual mode.
(18) Cam data/limit switch output data batch-change error flag (M2058)
................................................................................. Signal from PCPU to SCPU
(a) This flag is used to check whether an error occurred or not when the cam
data/limit switch output data were changed.
1) The flag remains OFF when there is no cam data/limit switch output data
error.
2) The flag turns ON on detection of a cam data/limit switch output data
error.
(b) Turning M2056 OFF also turns M2058 OFF.
(19) Speed change in progress flag (M2061 to M2092)
........................................................................Signal sent from PCPU to SCPU
This flag switches ON when a speed change (designated by a control change
(CHGV) instruction at the sequence program) is in progress. This flag should
be used for speed change program interlock purposes.
