(2) Program conditions
This program reads the digital output values that have been A/D converted using
CH1 and CH2 of the Q62AD-DGH. CH1 performs sampling processing, and CH2
performs averaging processing every 50 times. An error code appears in BCD if
a write error occurs.
(a) Initial settings
• A/D conversion enable channel ............. CH1, CH2
• Count-based
averaging processing channel .............. Average count setting of CH2
: 50 times
• 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
• 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, M1
• CH1 digital output value (32bit) ............................... D1, D2
• CH2 digital output value (32bit) ............................... D3, D4
• Warning output flag .................................................. D5
Process alarm ........................................................... M12, M13
