The ROC364.
Nothing Else Measures Up.

Power for the Toughest Applications. The ROC364 Remote Operations Controller (ROC) is a powerful microprocessor-based remote measurement and control device. It is ideal for medium to high point-count applications requiring sophisticated measurement and control capability. The ROC364 incorporates many outstanding features that make it easy to use, easy to customize to the application, and cost-effective for current and future needs.

Easy to Use. The ROC364 features versatile firmware that makes complex calculations, like those for gas flow measurement, simple to implement. Both 1985 and 1992 versions of AGA Reports No. 3 and 7 as well as AGA Reports No. 8 and NX-19 are supported. Likewise, sophisticated PID loop control and logic sequencing control schemes can be implemented without programming.

Engineers and operators can configure and operate the ROC364 easily from a laptop computer. These same activities can be performed in a host-based system, because the ROC364 is supported by leading software suppliers including Cygnet^TM, Intellution^®, USDATA^®, and Wonderware^TM to name just a few.

Easy to Customize. The ROC364 offers integrators a choice of native ROC, MODBUS, or custom communication protocols for seamless integration into new or existing automation systems. Polled, spontaneous report-by-exception, peer-to-peer, and master-slave communication strategies are incorporated.

Modular and Expandable.  Modular design makes the ROC364 cost-effective because it can be adapted to your changing needs. Up to 64 I/O points are accommodated with plug-in single-point modules that can be used in any combination of types--you buy only what you need, when you need it.

Also available is a fixed 32-point I/O card that replaces the I/O modules and module racks. Only one I/O card can be used with the ROC364.

In addition to an operator interface port, one or two plug-in communication cards extend your communication options to a host, other ROCs, or specialized equipment. EIA-232, EIA-422/485, radio modem, leased-line modem, or dial-up modem options are available.

For ease of software upgrades, the operating system and applications firmware reside in a FlashPAC memory module that can be re-programmed in the field.

Proven Technology. Low power consumption and a wide operating temperature range make the ROC364 suitable for solar-powered installations. Built-in self diagnostics and a watchdog timer help protect your application from erroneous outputs and aid troubleshooting.

Ruggedness is a requirement for field equipment and the ROC364 meets the challenge with its heavy-gauge steel enclosure, MIL-SPEC circuit boards, and gold-plated connectors. Limited surge protection is built into I/O modules and communication cards.

Exceptional Value. The ROC364 offers exceptional value that can be measured in terms of high return on investment, reduced product obsolescence, and a fully-defined migration path to the future. 

Specification Summary.

Input/Output

I/O Modules:  One to 16 I/O modules plug into one to four module racks. Modules can be any combination of these types: discrete input and output; analog input and output; pulse input; RTD input; relay output; HART^® Interface; and smart modules.
I/O Card:  One 32-point card can be used with a ROC364 exclusive of module racks.

Communications

Ports: One EIA-232 port for operator interface is standard. Two additional ports are available using any of these plug-in card types: EIA-232, EIA-422/485, radio modem, leased-line modem, dial-up modem.
Protocols: ROC, Modbus, and other protocols are available.
Local Display Panel: A local display panel for viewing key ROC parameters and data points is available.

Applications

AGA gas measurement for five meter runs
PID control with override for 16 loops
Logic/sequencing control using up to 4 Function Sequence Tables (FSTs)

Compliance
