(2) Program conditions
This program reads the digital output values that have been A/D converted using
CH1 to CH3 of the Q64AD-GH. CH1 performs sampling processing, CH2
performs averaging processing every 50 times, and CH3 performs primary delay
filtering at intervals of 100ms time constant. An error code appears in BCD if a
write error occurs.
(a) Initial settings
• A/D conversion enable channel ............. CH1 to CH3
• Count-based
averaging processing channel .............. Average count setting of CH2
• Primary delay filter-based
averaging processing channel .............. Time constant setting of CH3
• Process alarm channel .......................... Lower lower limit value setting of
• Rate alarm channel ................................ Period setting of CH3: 50ms
• Input signal error detection channel ...... Setting of CH1: 10%
(b) Devices used by the user

• Input signal error detection reset signal .................. X11
• Error reset signal ...................................................... X12
• Error code display (BCD 3 digits) ............................ Y20 to Y2B
• A/D conversion completed flag ................................ M0 to M2
• CH1 digital output value (32bit) ............................... D1, D2
• CH2 digital output value (32bit) ............................... D3, D4
• CH3 digital output value (32bit) ............................... D5, D6
• Warning output flag .................................................. D7
Process alarm.......................................................... M12, M13
Rate alarm ............................................................... M22, M23
• Input signal error detection flag ............................... D8, M30
