Description

SNAP Ethernet I/O™ systems with SNAP Ethernet and SNAP

wireless LAN brains. The SNAP-PID-V monitors input signals and

adjusts output signals to control one proportional-integral-derivative

(PID) loop, performing all necessary PID calculations

in the module itself.

loop with SNAP Ethernet I/O systems required an Opto 22 industrial

controller running an OptoControl™ strategy or a remote computer

running SCADA software. For non-Ethernet I/O units, the

multifunction B3000 brain could be used. The SNAP-PID-V module

makes this equipment unnecessary, since all PID calculations are

made in the module independent of a controller or other processor.

IO4AB system. However, PID functionality is available on all SNAP-

PAC brains that support IO4AB.

Applications

temperature, pressure level, flow, and process control. The SNAP-

PID-V is ideal for remote installations or other environments where

communication links are subject to interruption. Since PID calculations

run locally on the I/O module, PID loop control can continue

independently if the communication link to the I/O system is broken.

multiple PID loops must be controlled at one location. When multiple

PID loop calculations run on an industrial controller or computer, a

performance slowdown occurs. When additional SNAP-PID-V

modules are added to a SNAP rack, however, all modules continue to

perform PID loop calculations at a constant speed without system

degradation, providing a highly scalable solution. Up to twelve SNAP-

PID-V modules can be used on an Opto 22 16-module B-series

mounting rack.

Inputs and Outputs

setpoint and process variables. Analog inputs share a common

reference and are not isolated from each other. PID output, sharing

a common negative terminal, provides 4–20 mA current and 0–10

VDC voltage outputs. (The PID output value is calculated by the

module and then sent simultaneously to both 4–20 mA and 0–10
