4/4 Modicon Quantum automation platform High-speed counter modules Presentation The Quantum automation platform offers two processor-controlled high-speed counter modules, the 140EHC10500 module and the 140EHC20200 module. These modules independently count pulses at high speeds. They automatically report the count value to the CPU on every scan and, if the counter is installed in the local rack, they can update the CPU asynchronously to the scan (via the IMOD instruction in LL984 language). 140EHC10500 module The 140EHC10500 is a five-channel high-speed counter, which can be configured in one of four operating modes. This module is ideal for the incremental high-speed counting of pulses up to 100 kHz at 5 V c or 20 kHz at 24 V c . The operating mode for each channel can be configured easily via the zoom screen in Unity Pro. These operating modes can be defined as follows: b 32-bit event counters on one or all channels, with output mode specified (latched or timed) b 32-bit differential counters that use two channels per function - the difference between the count values on each channel is reported to the CPU. A module can be configured to handle two differential counters, two channels per function b 16-bit repetitive counters on one or all channels; the counter repeats the count after reaching the setpoint b 32-bit rate counters on one or all channels; the rate is sampled over a time interval specified as either 1 s or 100 ms The counter configuration also includes 8 outputs, each of which can be triggered by a setpoint or by a programmable count value in upcount/downcount operations. Each of the outputs can be configured as follows: b Output turns on at setpoint, either latched or as a one-shot b Output turns on at final value, either latched or as a one-shot b Output changes state on rising or falling edge applications b Output turns on after a specified time delay from a final count value (16,383 ms max.) 140EHC20200 module The 140EHC20200 is a 2-channel module best suited to high-speed counting applications up to 500 kHz or applications that require a quadrature encoder interface. The operating mode for each channel can be configured easily via the zoom screen in Unity Pro. These operating modes can be defined as follows: b 16-bit counters on one or both channels with two outputs, configurable in incremental or quadrature mode b 32-bit counters that use both channels with two outputs, configurable in incremental or quadrature mode b 32-bit counters on one or both channels with no outputs, configurable for incremental or quadrature mode b 16-bit counters on one or both channels with no outputs, in rate sampling mode for incremental or quadrature encoders When the counter configuration includes outputs, each can be triggered by a setpoint or by a programmable count value less than the setpoint in upcount/downcount operations. Each of the outputs can be configured as follows: b Output latched on at setpoint b Output latched on at final count value b Output timed on at setpoint, with a time range of 016,383 ms (only one of the four outputs can be configured in this mode) b Output timed on at final count value, with a time range of 016,383 ms (only one of the four outputs can be configured in this mode) CPUs: page 1/2 I/O architectures: page 2/6 I/O: page 3/2 Communication: page 5/2 Safety modules: page 6/2 2 1 3 4 5 6 7 8 9 10 2 1 3 4 5 6 7 8 9 10 2 1 3 4 5 6 10 2 1 3 4 5 6 10
