Digital input assignment for input control mode

You need to assign one or more digital inputs with non-exclusive associations to define the active tariff.

If a digital input is used for multi-tariff, it cannot be used for an exclusive association (such as Demand Sync or Input Metering), but digital inputs can be shared with a non-exclusive association (such as Alarms). To make a digital input available for setting tariffs, any conflicting associations must be manually removed at the source of the original association.

You cannot configure any digital input tariff if digital input 1 is not available for association. Likewise, digital input 2 must be available to select more than two tariffs.

The status of the digital inputs is used to calculate the binary value of the active tariff, where off = 0 and on = 1. The calculation of the number of tariffs value can differ, depending on the number of digital inputs that can be selected (i.e., inputs that can be associated with multi-tariff).

2 1 (digital input 1) 2 (digital input 1 and 2)
3 2 (digital input 1 and 2)
4 2 (digital input 1 and 2) 3 (digital input 1, 2 and 3)
5 3 (digital input 1, 2 and 3)
6 3 (digital input 1, 2 and 3)
7 3 (digital input 1, 2 and 3)
8 3 (digital input 1, 2 and 3) 4 (digital input 1, 2, 3 and 4)

Applicable for PM5570 / PM5660 / PM5661 / PM5760 / PM5761 meter models

Number of tariffs required Digital inputs required
Configuration 1 Configuration 2
1 1 (digital input 1)
2 1 (digital input 1) 2 (digital input 1 and 2)
3 2 (digital input 1 and 2)
4 2 (digital input 1 and 2) 2 (digital input 1 and 2)

Configuration 1: 8 tariff assignment using 3 digital inputs

Applicable for PM5650 meter model and PM5500 series except PM5570

NOTE: There is no inactive tariff with this configuration.
Tariff Digital input 4 Digital input 3 Digital input 2 Digital input 1
T1 N/A 0 0 0
T2 N/A 0 0 1
T3 N/A 0 1 0
T4 N/A 0 1 1
T5 N/A 1 0 0
T6 N/A 1 0 1
T7 N/A 1 1 0
T8 N/A 1 1 1

Configuration 1: 4 tariff assignment using 2 digital inputs

Applicable for PM5570 / PM5660 / PM5661 / PM5760 / PM5761 meter models

NOTE: There is no inactive tariff with this configuration.
Tariff Digital input 2 Digital input 1
T1 0 0
T2 0 1
T3 1 0
T4 1 1

Configuration 2: 8 tariff assignment using 4 digital inputs

Applicable for PM5650 meter model and PM5500 series except PM5570

NOTE: Digital input configuration 0000 means there are no active tariffs (all tariffs are disabled).
NOTE: Any configuration above T8 (i.e., 1001 and higher) is invalid and therefore ignored by the meter (the active tariff does not change).

Configuration 2: 3 tariff assignment using 2 digital inputs

Applicable for PM5570 / PM5660 / PM5661 / PM5760 / PM5761 meter models

NOTE: Digital input configuration 0000 means there are no active tariffs (all tariffs are disabled).
