:

The PM-24 module’s DC-to-DC converter supplies

approximately 12 volts to the backplane, which is reflected in

the on-screen values for points 1 through 3.

1.3.4 Options

The ROC800 allows you to choose from a wide variety of options to

suit many applications.

Optional communication modules include EIA-232 (RS-232) serial

communications, EIA-422/485 (RS-422/485) serial communications,

Multi-Variable Sensor (MVS), dial-up modem communications, and the

HART module (refer to

Chapter 5, Communications

).

The ROC800 can handle up to two MVS interface modules. Each

module can provide power and communications for up to six MVS

sensors, for a total of up to 12 MVS sensors per ROC800 (refer to

Chapter 5, Communications

).

Optional I/O modules include Analog Inputs (AI), Analog Outputs

(AO), Discrete Inputs (DI), Discrete Outputs (DO), Discrete Output

Relays (DOR), Pulse Inputs (PI), Resistance Temperature Detector

(RTD) Inputs, Thermocouple (T/C) Inputs, Advanced Pulse (APM), and

Alternating Current I/O (ACIO) (refer to

Chapter 4, Input/Output

Modules

).

The optional application license keys provide extended functionality,

such as the use of the DS800 Development Suite Software (the IEC

61131-3 compliant programming environment) and various user

programs, and enable embedded meter runs. For example, you need to

install a license key with the proper license in the ROC800 to perform

AGA calculations. Refer to

Section 1.6, DS800 Development Suite

Software

.

The Local Operator Interface (LOI local port) communications terminal

requires the installation of an LOI cable between the ROC800 and your

PC. The LOI port uses an RJ-45 connector with a standard EIA-232

(RS-232D) pin out.
