High-speed counters
The display system provides various high-speed counter
functions. These counter function blocks are coupled directly
to digital inputs. The high-speed counter functions are only
available with DC display I/O module.
The following functions are possible:
• Frequency counters, measure frequencies CF..
• High-speed counters, count high-speed signals CH..
• Incremental counter, count dual-channel incremental
encoder signals CI..
The high-speed digital inputs are I1 to I4.
The following wiring rules apply:
• I1: CF01 or CH01 or CI01
• I2: CF02 or CH02 or CI01
• I3: CF03 or CH03 or CI02
• I4: CF04 or CH04 or CI02
Example:
• I1: High-speed counter CH01
• I2: Frequency counter CF02
• I3: Incremental encoder channel A CI02
• I4: Incremental encoder channel B CI02
Caution!
Each digital input I .. may only be used once by the CF, CH,
CI function blocks.
The incremental encoder requires an input pair.
