Working with Scheduled Data
10.1.4
Downloading Scheduled Data with PSCSV
The 1133A always stores scheduled data in a 32 megabyte flash memory module for later review
and downloading. Users can download scheduled data through a network, over a modem, or on site
through one of the serial ports. Additionally, the 1133A can trigger on an imminent full-memory
condition to prevent data loss.
10.1.5
Logging Data with KYZ Pulse Metering
Featuring four, multimode contacts, the 1133A permits seven different operational modes, including
KYZ pulse metering. Once KYZ relays are configured and system power is connected to the voltage
and current inputs, the relays will start logging data.
For KYZ pulse metering, specify optional KYZ relays (Option 6) instead of standard mechanical
relays.
See Section 3.3 for details on relay options.
Relay specifications are located under
“Programmable Contact Output Connections” in Chapter 12. To configure KYZ pulse metering,
see “Configuring KYZ Pulse Metering” in Section 7.10.
10.2
Logging Scheduled Data using Other Protocols
10.2.1
DNP 3.0 and Modbus Protocols
Logging scheduled data under DNP 3.0 and Modbus requires additional, third party software
designed to connect to devices that use these protocols and communicate using a serial port or
the Ethernet. Prior to actually retrieving any scheduled data it is essential to configure the 1133A
communications ports for the desired protocol. Use PSCSV to configure the 1133A for DNP 3.0 or
Modbus. For information on configuring these ports for DNP or Modbus protocols see “Configuring
the 1133A”, and “Configuring DNP 3.0 Protocol” or “Configuring Modbus Protocol” starting in
Section 7.6.
Once configured, the third party software will need to open the specific port on the 1133A to
establish communications. After establishing communications, determine the codes that specify
data items that you are seeking to download. To identify the codes that correspond to these data
items, consult the tables in Appendix A, DNP 3.0 and Modbus Data Structure.
10.2.2
Checking the Flash Memory Status
Flash memory in the 1133A is set up so that it can be configured to store two types of data:
Scheduled and Event. To store scheduled data, the scheduled partition of the flash memory module
must have some space allocated to it through PSCSV. PSCSV allows you to partition the entire
flash module as a percentage of the whole for Event data and Scheduled data. A slider in the
PSCSV Flash Memory Configuration window provides this means of changing the size of the flash
partitions. See Figure 10.1.
Prior to actually configuring the flash module partitions, it would be good to check the flash
memory status for any data that may be residing in flash, in case it needs to be downloaded from
flash to a computer.
