(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
: 50 times
• Primary delay filter-based
averaging processing channel ..............Time constant setting of CH3
: 100ms
• Process alarm channel ..........................Lower lower limit value setting of
CH2: 1000
Lower upper limit value setting
: 1500
Upper lower limit value setting
: 6000
Upper upper limit value setting
: 7000
• Rate alarm channel................................Period setting of CH3: 50ms
Upper limit value setting: 0.3%
Lower limit value setting: 0.1%
• Input signal error detection channel ......Setting of CH1: 10%
(b) Devices used by the user
• Digital output value read command input signal .....X10
• 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
• Error code.................................................................D9
