4.1 Product Specifications
The Enhanced Generic ASCII Serial Communication Modules allow Rockwell
Automation
®
ControlLogix
®
Programmable Automation Controllers (PACs) to
easily interface with serial devices using non-specific ASCII character text string
or byte value serial communication protocols.
MVI56E-GSC enhancements include local and remote diagnostics through the
module’s Ethernet port, and CIPconnect
®
technology for bridging though
Rockwell Automation ControlNet™and EtherNet/IP™ networks.
The MVI56E-GSC module is a fast and easy way to add two fully configurable
serial communication ports to the ControlLogix platform, eliminating the need to
use the front port of the processor, or consume valuable processor time sending
and receiving serial messages.
The module is a single-slot, backplane-compatible solution. Each port is capable
of sending and receiving large ASCII character strings or byte streams of up to
4096 characters or bytes. Many different serial communication devices can be
integrated into the ControlLogix platform by building upon the sample ladder logic
provided for this module.
4.1.1 General Specifications
 Backward-compatible with previous MVI56-GSC version
 Single Slot - 1756 ControlLogix
®
backplane compatible
 10/100 MB Ethernet port for network configuration and diagnostics with Auto
Cable Crossover Detection
 User-definable module data memory mapping of up to 10,000 16-bit registers
