(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
