Preface
Thank you for purchasing Digital Corporation's Pro-face Graphic Logic Controller
GLC2400 (referred as "GLC" from here on).
This controller features a number of improvements over the previous GLC series
including enhanced functions and advanced operability. Flex Network communi-
cation, Ethernet, CF Card and Sound output are available for the GLC2400 with-
out having to purchase and mount an extension unit.
Please read this manual carefully as it explains, step by step, how to use the GLC
correctly and safely.
Also, in this manual's examples, the Mitsubishi MELSEC-AnA Series PLC is
used whenever possible, connected in a one-to-one relationship with a GLC.

  • Page 6: Essential Safety Precautions

    Preface Essential Safety Precautions This guide contains a variety of safety markings for safe and correct operation of this Unit. Please read this installation guide and any related manuals carefully to fully understand how to correctly use this Unit's functions. ! Safety Symbols Please pay attention to these symbols and follow all instructions given.
  • Page 7 Preface DANGERS (2) Whenever the GLC generates a “Watchdog Timer Error”, GLC operation will halt. Also, when Errors occur in Input/ Output control areas that the GLC cannot detect, it is possible for unexpected movement to occur in those areas. As a result, for the purpose of preventing unsafe machine movement, a “Failsafe Circuit”...
  • Page 8 Preface DANGERS - Please design your system so that equipment will not mal- function due to a communication fault between the GLC and its host controller. This is to prevent any possibility of bodily injury or material damage. - The GLC is not appropriate for use with aircraft control devices' or medical life support equipment, central trunk data transmission (communication) devices, nuclear power control devices, or medical life support equipment,...
  • Page 9 Preface WARNINGS Installation Warnings: - High voltage runs through the GLC. Except for replacing the backlight, never disassemble the GLC, otherwise an electric shock can occur. - Do not modify the GLC unit. Doing so may cause a fire or an electric shock.
  • Page 10 Preface WARNINGS - The GLC uses a lithium battery for backing up its internal clock and control memory data. If the battery is incor- rectly replaced (i.e. the + and - sides are reversed), the battery may explode. Therefore, before changing the bat- tery, Digital recommends that you contact your local GLC distributor for battery replacement instructions.
  • Page 11 Preface CAUTIONS - Be sure that metal filings or wiring remnants do not fall inside the GLC, since they can cause a fire, accident, or malfunction. GLC Operation and Maintenance Cautions - Be sure to read the GLC’s manual and on-line help infor- mation carefully before performing program changes, forced output, or utilizing the RUN, STOP or PAUSE com- mands while the GLC is in operation.
