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.
