This chapter describes QD62 (E/D) programs, whose system configuration example
shown below, in the following two cases:
• GX Configurator-CT is used
• GX Configurator-CT is not used
When applying any of the program examples introduced in this chapter to the actual
system, verify the applicability and confirm that no problem occurs in the system
control.
(1) System configuration
QD62
(X/Y0 to X/YF)
(2) Setting conditions of the intelligent function module switch
Set the pulse input mode, counting speed setting, and counter format with the
intelligent function module switch on GX Developer. (See Section 4.5.)
Item
CH1
(3) Program conditions
This program uses QD62 to perform counting with the conditions listed below.
Preset value
Coincidence output point No. 1
Ring counter minimum value
Ring counter maximum value
Sampling time setting
Periodic pulse time setting
1 Set only when a ring counter function is used
2 Set only when the sampling counter function is used
3 Set only when the periodic pulse counter function is used
POINT
Programs that were used in earlier products such as A1SD62(E/D/D-S1) cannot be
used because the I/O signals and the buffer memory configuration of these
products differ from those of QD62(E/D). The conventional dedicated instructions
cannot be used.
QX10 (X10 to X1F)
QY10 (Y20 to Y2F)
Pulse input mode
2-phase multiple of 1
