Smart Setup Registers
The meter has three smart setup registers to configure smart input modules. Smart input module IC02 requires only smart register
1 to be set up, while IC03 requires smart registers 1 and 2 to be set up. Figure 2 sho ws the functions of quadr ature smar t input modules IC02 and IC03 with input signals from a standard quadr ature encoder.

Smart Register 1
Smart register 1 allows you to select either the quadrature, combined, or independent counting mode for input signals A and B. Input signal C is the control mode for input signals A and B to capture, gate, zero, reset, or start the counters and is also selected through smart register 1. Input signal C can also be set as an independent counter without control o ver input signals A and B.
The resultant count produced by each mode is stored in the smar t register output map in pr imary, secondary, capture or gate counters. Any of the counters can be tr ansferred to Channel 1 via Code 2, to Channel 2 via Code 4, to Channel 3 via Code 5, and to Channel 4 via Code 6.
Smart Register 2 (IC03 Only) Smart register 2 allows you to select the setpoint control settings of smar t relay 1 (SR1) and smar t relay 2 (SR2) using either the primary, secondary, capture, or gate counters of the smar t register 2 output map. All other settings f or SR1 are configured via setpoint 5 and for SR2 via setpoint 6 in the meter s setpoint programming mode.

Counter Functions
Counter inputs A, B, and C can be portrayed as a train of pulses having a rising edge ( ) between a low and high signal level. Depending on the counter function selected, these inputs may vary in phase to each other. In the case of a shaft encoder, the A signal lags the B signal by 90 and the primary counter decrements when the shaft is rotated clockwise. To change the direction of rotation to countercloc kwise, reverse the A and B signal inputs at the connector (see Figure 1). The C signal occurs once per revolution.

Quadrature Modes
The quadrature modes are shown for a shaft encoder as an example. Depending on the direction of rotation, the A signal leads or lags the B signal.
Using the same shaft encoder, the angular / linear resolution of the x1 Mode can be increased b y 2 using the x2 Mode, or by 4 using the x4 Mode.

C Signal Functions
C signal functions operate with the A and B signal functions and influence the pr imary and secondary gate and capture counters.
Capture A, B Mode The capture A, B mode provides a snapshot of the pr imary and secondary counters. It is a straight transfer of the values from the primary and secondary counters to primary and secondary capture.
See Figure 15.
Note:
The primary and secondary counters are not affected by the operation and no counts are lost.
The primary counter value is loaded into primary capture on a falling edge (
) C signal.
The secondary counter value is loaded into secondary capture ) C signal. on a falling edge (
Application:
This mode is useful to capture positional inf ormation in relation to an e xternal event. To track if an y errors occur, the positi onal information could be used as a ref erence that the encoder can be compared against.
Figure 15 Capture A, B Mode
Gate Count A, B In this mode the primary and secondary gate counters are updated with the number of pulses that occur in the primary (A signal) and secondary (B signal) counters respectively between consecutive falling edge C signal pulses. The primary and secondary counters are not reset and continue to count after each update of the gate counters. The gate count A, B mode oper ates as follows:
See Figure 16.
The value in the primary counter on the pre vious falling edge (
) C signal is subtracted from the v alue in the primary counter on the ) C signal and loaded into the primary gate counter. The primary counter continues to count up and is not
most recent falling edge ( reset after each event.
The value in the secondary counter on the previous falling edge (
) C signal is subtracted from the value in the secondary counter on ) C signal and loaded into the secondary gate counter. The secondary counter continues to count up
the most recent falling edge ( and is not reset after each e vent.
Note:
The gate secondary counter is only updated in the A & B independent mode.
Application:
This mode is
useful to capture
rate inf ormation
in relation to an external e vent.
For e xample, you may want to know ho w m uch product was produced per shift.
At the star t of the shift, the
operator could
set a s witch and reset it at the end of the shift.
The resultant

would let y ou know ho w m uch was produced
during that shift.

Gate Count & Reset A, B Mode In this mode the pr imary and secondary gate counters are again updated with the n umber of pulses that occur in the pr imary (A signal) and secondar y (B signal) counters respectiv ely between consecutive falling edge C signal pulses. But, in this case, the pr imary and secondary counters are reset after each update of the gate counters. The gate count & reset mode oper ates as follows:
See Figure 17.
The value in the primary counter on the pre vious falling edge (
) C signal is subtracted from the v alue in the primary counter on the ) C signal and loaded into the primary gate counter. The primary counter stops counting after each f alling
most recent falling edge ( edge C signal event and is reset to 0.
The value in the secondary counter on the previous falling edge (
) C signal is subtracted from the value in the secondary counter on ) C signal and loaded into the secondary gate counter. The secondary counter stops counting after each
the most recent falling edge ( falling edge C signal event and is reset to 0.
Figure 17 Snapshot of Gate Count & Reset Mode
Reset to Offset & Star t A, B Mode
In this mode the primary and secondary counters are reset to the value stored in the meters primary and secondary reset offset registers (registers 121 and 122 respectively). Primary and secondary counters continue counting after being reset to the reset offset values.
The reset to offset & star t A, B mode operates as follows:
See Figure 18.
The pr imary and secondar y counrising
ters begin counting on a edge (
) C signal.
On a falling edge (
) C signal the
primary counter is reset to the value stored in the primary reset offset register (121), and the secondary counter reset to the v alue stored in the secondary reset offset register (122).
Figure 18 Reset to Offset & Star t Mode
The default setting of the pr imary and secondary reset offset registers is 0. To change the value stored in these registers:
Connect the meter to a PC r unning a terminal program.
Start the terminal program.
Access register 121 and change the offset to the required v alue.
Access register 122 and change the offset to the required v alue.
See Registers Supplement (NZ209), Registers 121 and 122 Reset Offset Registers, for a detailed description of the reset offset registers.

Application:
This mode is useful f or when an e xternal reset is required. For example, A pushbutton on the C input can be used to reset to 0, or forward the counter to a kno wn count. The counter starts again when the button is released.
C Count Mode
In this mode the primary counter increments on a rising edge (
) C signal only.
See Figure 19.
Application:
This mode is useful for multi-input systems.
Figure 19 C Count Mode
Reset to Offset A, B Mode In this mode the primary and secondary counters are also reset to the value stored in the meters primary and secondary reset offset registers (registers 121 and 122 respectiv ely). But, in this mode, the pr imary and secondar y counters contin ue counting after be ing reset to the reset offset v alues.
See Figure 20.
The reset to offset A, B mode oper ates as follows:
On a falling edge (
) C signal the primary counter is reset to the value stored in the primary reset offset register (121), and the secondary counter reset to the value stored in the secondary reset offset register (122).
The pr imary and secondar y counters contin ue to count on
being reset.
Application:
This mode is useful for setting a position to a known reference position. For example, a microswitch can be positioned at home and used as an input to C on a milling tab le. Now every time the home position is encountered, the counter is set to a kno wn position.
