About this Manual:
This manual covers specifications and procedures necessary for the installation and operation of the
C200H-CT001-V1 and C200H-CT002 High-speed Counter Units. It includes example system configu-
rations to ease the implementation cycle. The C200H-CT001-V1 and C200H-CT002 are Special I/O
Units for C200H PCs. The C200H-CT001-V1 is a high-speed, reversible counter capable of counting
at a maximum of 50 kcps. The C200H-CT002 is a high-speed, reversible counter capable of counting
at a maximum of 75 kcps.
Please read this manual carefully and be sure you understand the information provided before attempting
to install and operate the C200H-CT001-V1 and C200H-CT002 High-speed Counter Units.
Section 1 contains a brief description of the Units and how they can be used. The Units are displayed
and their indicators are explained. An example system configuration is included to demonstrate Unit
application. The operating modes and their associated ranges of operation are also described.
Section 2 shows the Unit settings and connector cable pin specifications. Instructions for the con-
struction of input and output connectors are provided. Electrical schematics and examples are pres-
ented to further explain Unit operation.
Section 3 describes the operational flow of the counting system. The input types are identified along
with instructions for their use. Data transfer timing is described in relation to the PC cycle time.
Section 4 describes the various operating modes in detail. Each mode is described by data alloca-
tion, timing charts, commands, flags, and examples. Data formats are explained.
Section 5 presents possible errors and solutions and describes how to handle errors from the PC.
The AR area Error and Restart Flags are described.
The following Appendices are also provided: Error Codes, Specifications, IR Area Allocations, and
DM Area Coding Sheets.
WARNING Failure to read and understand the information provided in this manual may result in
personal injury or death, damage to the product, or product failure. Please read each
section in its entirety and be sure you understand the information provided in the section
and related sections before attempting any of the procedures or operations given.
