Page 8: The Purpose Of Io Modules
1.1 The Purpose of IO Modules Acuvim II meter does not have any IO functions itself, but it can realize multi IO functions with IO modules, such as digital input, counter of pulses, relay output, analog output, and analog input and so on. There are three types of IO modules, AXM-IO1, AXM-IO2 and AXM-IO3. - Page 9 4 digital inputs (DI), each digital input can be used to detect remote signals, or be used as a counter of input pulses. When it is used to detect remote signals, it also can enable SOE(sequence of events), recording the events and time of the events.

Page 24: Detection Of Remote Signals
Figure 3-1 shows the function of IO modules, which is explicated in utility software as follows, where AXM-IO12 (AXM-IO1 module in sub address 1), AXM-IO22 (AXM-IO2 module in sub address 1) and AXM-IO32 (AXM-IO3 module in sub address 1) are linked to Acuvim II meter. Figure 3-1functions of IO modules 3.1 Detection of Remote Signals The digital input circuit can be set to detect remote signals. - Page 25 Figure 3-2 showing DI state on screen 2. Record of SOE When digital input circuit is set to detect remote signals, function of record of SOE can be enabled. So when the remote signals change, IO module can record changing information, such as the time and the change.
- Page 26 When the IO module in which SOE function is enabled is changed, the SOE records will lose. All group of SOE records have the same data style. Take the first group of SOE records for example, “4399H to 439fH” registers record the time information, including year, month, day, hour, minute, second and millisecond.
- Page 27 Figure 3-3 data information of SOE records read by the utility software 3. Parameter Setting of Detection of Remote Signals Take parameter setting of AXM-IO11 (AXM-IO1 module in sub address 0) for example. “109eH” register: this register is an unsigned integer, where bit0 determines DI1’s working mode, bit1 determines DI2’s working mode, and so on.
- Page 28 IO module is SOE disabled. If register is “1”, then AXM-IO11 (AXM-IO1 module in sub address 0) is SOE enabled. If register is “2”, then AXM- IO21 (AXM-IO2 module in sub address 0) is SOE enabled. If register is “3”, then AXM-IO31 (AXM-IO3 module in sub address 0) is SOE enabled. If register is “4”, then AXM-IO12 (AXM-IO1 module in sub address 1) is SOE enabled.

Figure 3-4 parameters setting of IO module’s SOE function 3.2 Counter of Pulses The digital input circuit can also be set to be counter of pulses. Recorded number of pulses: including “4349H to 4380H” address registers. “4349H to 4380H” registers record 28 groups of number of pulses, including 6 groups of records for AXM-IO11 (AXM-IO1 module in sub address 0), 4 groups of records for AXM-IO21 (AXM-IO2 module in sub... - Page 30 address 0), 4 groups of records for AXM-IO31 (AXM-IO3 module in sub address 0), 6 groups of records for AXM-IO12 (AXM-IO1 module in sub address 1), 4 groups of records for AXM-IO22 (AXM-IO2 module in sub address 1) and 4 groups of records for AXM-IO32 (AXM-IO3 module in sub address 1) in sequence.
- Page 31 Figure 3-6 recorded number of pulses read by the utility software Parameter Setting of Counting of Input Pulses: Take AXM-IO11 (AXM-IO1 module in sub address 0) for example. 1. “109eH” register: if the bit is set as “1”, the counterpart digital input circuit is set to be a counter of input pulses.

Page 32: Relay Output
For example, if A=20, the recorded number of pulses counted by DI1 circuit of AXM-IO11 is 100 (4349H to 434aH registers), then the real number of pulses is 20×100=2000. The parameter setting is shown in figure 3-13. 3.3 Relay Output Relays in IO modules can work in two different modes, one is controlling mode, and the other is alarm mode. - Page 33 Figure 3-7 states of relays read on screen 2. Parameter Setting Take AXM-IO11 (AXM-IO1 module in sub address 0) for example. “RO working mode (10a0H)” register: this register determines the working mode of relays. If the register is “0”, then RO1 and RO2 will work in controlling mode.

then be switched off. The parameter setting is shown in figure 3-13. 3.4 Digital Output There are two modes selection for digital output circuit, one is alarm mode, and the other is energy output mode. For alarm mode, action of digital output circuit is controlled by whether the alarm is occurred or not. - Page 35 “DO2 output type (10a8H)” register: when DO circuits work in energy output mode, this register determines the energy output type for DO2. The value of this register is defined as the same as “DO1 output type” register. “DO1 output type” register and “DO2 output type” register can be set to the same value or not.

When DO circuits work in energy output mode, parameters of DO energy pulse constant should also be set correctly, which include “active pulse constant (100aH)” and “reactive pulse constant (100bH)”, as shown in figure 3-8. The value of pulse constant should satisfy following expression: Pmax DO Pulse Width Pulse constant >(... - Page 37 23.2 23.2 23.2 23.2 23.2 23.2 23.2 23.2 -2000 2000 2800 6000 7200 -6000 6000 8400 2000 2400 0.5C 0.5L Total Apparent Phase Active/Reactive Frequency(Hz) Total Active/Reactive Phase Apparent Phase Voltage(V) Line Voltage(V) Current(A) Power Factor Power(VA) Power(W/Var) Power(W/Var) Power(VA) 4-20mA output mode -2000 2000 2800...

“Electrical quantities relative to AO1 (10c2H)” register: this register determines which electrical quantity AO1 should be relative to. It is explicated in Acuvim II User’s Manual. For example, if this register is “0”, then AO1 is relative to “Frequency”. “Electrical quantities relative to AO2 (10c3H)” register: this register determines which electrical quantity AO2 should be relative to. - Page 40 AI Value AI Value AI Value AI Value 4095 4095 4095 4095 20 mA 20 mA Figure 3-11 relationship between AI value and input analog value Figure 3-12 AI value read on screen 2.
