SECTION 1 - INTRODUCTION
OVERVIEW
The Remote I/O Module (IMRIO02) operates with the Bailey
Multi-Function Processor (IMMFP01/02/03) to provide power-
ful control capabilities on a plant wide scale. The Remote I/O
module is designed for communication between an MFP and
remotely located slave modules.
INTENDED USER
System engineers and technicians should carefully read and
understand this manual before installing and placing the RIO
Module into service. Once familiar with the operation of the
RIO, the tables and illustrations in this manual provide a con-
cise reference of information.
MODULE DESCRIPTION
The RIO occupies one slot in the Module Mounting Unit (MMU).
Dipswitches on the RIO configure user options and module
addresses. LEDs on the front panel provide operating status.
Two captive screws on the module faceplate secure it to the
MMU. The user connects the communication cabling to the ter-
mination unit/module which is connected to the RIO.
FEATURES
The Remote Input/Output Module (RIO02) provides communi-
cation between the Multi-Function Processor and remote slave
modules at a rate of one Megabit per second. A RIO on each
end of the link supports communication up to 10,000 feet
(3,000 meters) to the farthest remote drop. The remote link can
be coaxial, twinaxial or fiber optic cable. The RIO also has
internal diagnostics which ensure module and communication
link integrity. The RIO hardware provides the capability to add
redundant modules and communication hardware.
MODULE APPLICATION
The Remote I/O Module (IMRIO02) provides the multi-function
processors with remote process control capability. The RIO
allows central control of slave modules up to 10,000 feet (3,000
meters) from the MFP (see Figures 1-1 and 1-2). Limitations on
this maximum distance depend on the cable type of the system
(refer to
). The Remote I/O Module also supplies addi-
tional links between the MFP and Digital Indicator Stations.
