Red Lion PAXCDC3 (DEVICENET) - Manual (Page 4)

(MMR) Auto/Manual Mode Register [23]
(PAXI/PAXCK/PAXDP/PAX2A/PAXDR)
This attribute sets the controlling mode for the outputs. In Auto Mode (0) the
meter controls the setpoint output. In Manual Mode (1) the outputs are defined
by the attribute SOR. When transferring from auto mode to manual mode, the
meter holds the last output value (until the attribute is changed by a write). Each
output may be independently changed to auto or manual. Select values to place
in manual mode by writing appropriate value to attribute 23. The bit position
definitions are:
Example:
1. Select manual mode for all outputs and AOR (PAXI/PAXDP/PAX2A/
PAXDR):
Value to write to attribute 23: 001Fh
(SOR) Setpoint Output Register [25]
(PAXI/PAXCK/PAXDP/PAX2A/PAXDR)
This attribute is used to view or change the states of the setpoint outputs.
Reading from this attribute will show the present state of all the setpoint outputs.
A “0” in the setpoint location means the output is inactive and a “1” means the
output is active.
In Automatic Mode (See MMR Description), the meter controls the setpoint
output state. In Manual Mode, writing to this attribute will change the output
state. The bit position definitions are:
Examples:
1. Turn all outputs on:
Value to write to attribute 25 - 000Fh.
2. Turn outputs 1, 3 on:
Value to write to attribute 25 - 0005h.
3. Turn all outputs off:
Value to write to attribute 25 - 0000h.
(AOR) Analog Output Register (Not PAXCK)
The Analog Output Register controls the analog output of the meter. The
manual mode must first be engaged by setting bit 4 of the CSR (PAX) or bit 0
of the MMR (PAXI). The range of values of this attribute is 0 to 4095, which
corresponds to 0 mA, 0 V and 20 mA, 10 V; respectively. If a value larger than
4095 is written to the AOR Attribute, 4095 will be loaded. The table lists
correspondence of the output signal with the attribute value.
*Due to the absolute accuracy rating
and resolution of the output card, the
actual output signal may differ 0.15% FS
from the table values. The output signal
corresponds to the range selected (20 mA
or 10 V).
Writing to this attribute while the meter is in the manual mode causes the output
signal to update immediately. While in the automatic mode, this attribute may be
written to, but the output will not update until the meter is placed in manual mode.
Examples:
1. Set output to full scale:
Value to write to attribute 15 (PAX) or attribute 24 (PAXI) - 0FFFh (4095).
2. Set output to zero scale:
Value to write to attribute 15 (PAX) or attribute 24 (PAXI) - 0000h (0).
