2-4 Master Controller Unit, I/O Module Rack, and Wiring Rev Jun/05

The firmware is programmed into flash memory at the factory, but can be reprogrammed in the field.

The application programs are configured by using ROCLINK configuration software including user

programs, such as the Modbus communications protocol.

When used with ROCLINK configuration software, a FlashPAC module can save a configuration to

disk as an .FCF file and later restore these configuration files into a ROC.

The RAM in a FlashPAC can store 87 history points, each holding 35 days of hourly values. Besides

storing history data, the RAM in a FlashPAC stores user program data. The flash ROM portion of the

FlashPAC is programmed with firmware at the factory and can store user programs downloaded through

a communications port.

Table 2-1, ROC Memory Map, on page 2-4 shows how the ROC memory is allocated. Each memory

location range (for example, 00000 to 1FFFF) represents 128 kilobytes of memory.

Determining FlashPAC Version

To determine the version of a FlashPAC, use ROCLINK configuration software. Select ROC >

Information > Other Information > Version Name, which contains the part and version numbers.



NOTE: The version may have been updated by a download of upgrade firmware into the module,

so the label on the actual FlashPAC module might not be accurate.

2.2.3 Diagnostic Inputs and Auxiliary Outputs

The ROC364 MCU monitors the power input voltages, transmitter output voltage, and the board temperature

with diagnostic Analog Inputs designated as “E” points by the configuration software. The inputs can be

calibrated by using ROCLINK configuration software. Two auxiliary Discrete Outputs are also available.

The diagnostic Analog Inputs and auxiliary Discrete Outputs are:

♦ Transmitter supply output voltage – Point Number E1.

♦ Power input voltage – Point Number E2.

♦ Auxiliary Discrete Output #1 – Point Number E3.

♦ Auxiliary Discrete Output #2 – Point Number E4.

♦ MCU board temperature – Point Number E5.
