Generating Energy Pulses through Relay Outputs
To generate energy pulses through a relay output:
1. Select a source accumulator (type of energy) and the pulse rate
for your output in the Energy Pulses setup, and then store it to
your device.
2. In the Relay Outputs setup (see
33
Programming Relay Outputs ),
configure a relay output, through which you want to deliver pulses,
to operate in pulse or KYZ mode, select a polarity (active pulse
edge) for energy pulses and a pulse width, and then select your
type of energy pulses as a pulse source for the relay. Store your
new setup to the device.
Configuring Digital Inputs
The SA300 supports up to three expansion Digital Input (DI) modules with a total of
48 digital inputs (DI1 to DI48). I/O numbers are automatically assigned to the inputs
in the order of connection when the device is powered up. For example, if two DI
modules are connected to the device, the digital inputs DI1-DI16 belong to the first
module, and DI17-DI32 - to the following module. If you insert an I/O module into
another slot position and do not change its order, then all digital inputs on the module
retain their I/O numbers.
To configure the digital inputs in your device, select the device site from the list box
on the PAS toolbar, select General Setup from the Meter Setup menu, and then click
on the Digital Inputs tab. The digital inputs that are not present in your device are
designated as not available.
The available options are described in the following table:
