4. Using High-speed Counter Modules
1) Number of Modules
a) The following I/O references are necessary in the CPU Module for each High-speed
Counter Module.
• 16 consecutive input relays
• 16 consecutive output coils
• 4 consecutive input registers
• 4 consecutive output registers
b) Therefore, the number of High-speed Counter Modules that can be used is deter-
mined by how many of the above I/O references are available in the CPU Module.
2) Installation Locations
a) A High-speed Counter Module can be mounted to any slot of the Mounting Base of
any Rack. It will occupy on slot.
b) The following diagram shows where to mount a High-speed Counter Module.
