M20 - LIMIT THRESHOLDS (LIMn, n=1...16)
P20.n.01 Reference measurement
P20.n.02 Channel number x
P20.n.03 Function
P20.n.04 Upper threshold
P20.n.05 Multiplier
P20.n.06 Delay
P20.n.07 Lower threshold
P20.n.08 Multiplier
P20.n.09 Delay
P20.n.10 Idle state
P20.n.11 Memory
Note: This menu is divided into 16 sections for the limit thresholds LIM1...16
P20.n.01 – Defines to which DCRG8 measurements the limit threshold applies.
P20.n.02 – The channel is defined when the reference measurement is an internal multichannel measurement (AINx for example).
P20.n.03 – Defines the operating mode of the limit threshold.
Max = LIMn enabled when the measurement exceeds P20.n.04 and P20.n.07 is the reset threshold.
Min = LIMn enabled when the measurement is less than P20.n.07 and P20.n.04 is the reset threshold.
Min+Max = LIMn enabled when the measurement is greater than P20.n.04 or less than P20.n.07.
P20.n.04 - P20.n.05 – Define the upper threshold, obtained by multiplying value P20.n.04 by P20.n.05.
P20.n.06 – Upper threshold tripping delay.
P20.n.07...P08.n.09 – As above but referred to the lower threshold.
P20.n.10 – Inverts the state of limit LIMn.
P20.n.11 – Defines whether the threshold remains latched and is cleared manually through commands menu (in ON) or if it resets automatically (in OFF).
M21 - COUNTERS (CNTn, n=1...8)
P21.n.01 Count source
P21.n.02 Channel number x
P21.n.03 Multiplier
P21.n.04 Divisor
P21.n.05 Description of the counter
P21.n.06 Unit of measure
P21.n.07 Reset source
P21.n.08 Channel number x
Note: This menu is divided into 8 sections for counters CNT1...8.
P21.n.01 – Signal that increments the count (on rising edge). This can be at DCRG8 power up (ON), when a threshold is exceeded (LIMx) or an external input
is enabled (INPx), etc.
P21.n.02 – Channel number x with reference to the previous parameter.
P21.n.03 – Multiplier K. The counted pulses are multiplied by this value before being displayed.
P21.n.04 – Fractional K. The counted pulses are divided by this value before being displayed. If other than 1, the counter is displayed with 2 decimal points.
P21.n.05 – Counter description. 16-character free text.
P21.n.06 – Counter unit of measure. 6-character free text.
P21.n.07 – Signal that clears the count. As long as this signal is enabled, the count remains at zero.
P21.n.08 – Channel number x with reference to the previous parameter.
