High-speed counters
EZD provides various high-speed counter functions. These
counter function blocks are coupled directly to the digital
inputs. The high-speed counter functions are only available
with EZDDC inputs.
The following functions are possible:
• Frequency counters, measure frequencies
CF..
• High-speed counters, count high-speed signals
CH..
• Incremental encoder counters, count two-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
Attention!
Every digital input I .. may only be used once by the CF, CH,
CI function blocks.
The incremental encoder requires an input pair.
