EtherCAT oversampling: maximum sampling rates irrespective of the EtherCAT cycle time

EtherCAT oversampling: maximum sampling rates irrespective of the EtherCAT cycle time

The oversampling principle is implemented in some EtherCAT devices. As a result, the operations of input or output modules are executed several times in each EtherCAT cycle. This allows a view of the machine processes in each EtherCAT cycle that is much more finely resolved in terms of time in comparison with conventional single-sampling operation.

EL1262 | EtherCAT Terminal, 2-channel digital input, 24 V DC, 1 µs, oversampling

EL1262 | EtherCAT Terminal, 2-channel digital input, 24 V DC, 1 µs, oversampling

The EL1262 digital input terminal acquires the fast binary 24 V control signals from the process level and transmits them, in an electrically isolated form, to the controller. The EtherCAT Terminal has two channels that indicate their signal state via light emitting diodes. The signals are sampled with a configurable, integer multiple (oversampling factor: n) of the bus cycle frequency (n microcycles per bus cycle). For each bus cycle, the EtherCAT Terminal generates a process data block that is transferred collectively during the next bus cycle. The timebase of the terminal can be synchronized precisely with other EtherCAT devices via distributed clocks. This XFC procedure enables the temporal resolution of the digital input signals to be increased to n times the bus cycle time.

EL1262-0050 | EtherCAT Terminal, 2-channel digital input, 5 V DC, 1 µs, oversampling

The EL1262-0050 digital input terminal acquires the fast binary 5 V control signals from the process level and transmits them, in an electrically isolated form, to the controller. The EtherCAT Terminal has two channels that indicate their signal state via light emitting diodes. The signals are sampled with a configurable, integer multiple (oversampling factor: n) of the bus cycle frequency (n microcycles per bus cycle). For each bus cycle, the EtherCAT Terminal generates a process data block that is transferred collectively during the next bus cycle. The timebase of the terminal can be synchronized precisely with other EtherCAT devices via distributed clocks. This XFC procedure enables the temporal resolution of the digital input signals to be increased to n times the bus cycle time. The switching thresholds of the input circuit are based on the CMOS level: Signal voltage "0" < 0.8 V, signal voltage "1" > 2.4 V. The 5 V supply voltage can be generated by the EL9505 power supply terminal and fed into the power contacts.

EL2262 | EtherCAT Terminal, 2-channel digital output, 24 V DC, 0.5 A, oversampling

The EL2262 digital output terminal connects the binary control output signals at the process level with electrical isolation. The outputs are controlled with an adjustable integral multiple (oversampling factor: n) of the bus cycle frequency (n microcycles per bus cycle). For each bus cycle, the EtherCAT Terminal receives a process data block that is output consecutively. The timebase of the terminal can be synchronized precisely with other EtherCAT devices via distributed clocks. An output pattern with a significantly higher pulse sequence than the bus cycle time is thus output precisely with the system-wide timebase. This procedure enables the temporal resolution of the digital output signals to be increased to n times the bus cycle time. The maximum output rate is 1 Msamples/s.

The EtherCAT Terminals from the ELM series were developed in order to enable the high-quality measurement of common electrical signals in the industrial environment. Flexibly usable measurement modules are especially useful in laboratory and testing technology environments. Therefore the ELM370x multi-function modules feature an input circuit that can be set to over 30 different types of electrical connection via EtherCAT: from voltages of ±60 V to ±20 mV, thus supporting thermocouples and IEPE, a current of ±20 mA, a resistance measurement of 5 kΩ and thus also temperature RTDs (Pt100, etc.), measuring bridges and potentiometers, and all of this with a 2- to 6-wire connection, depending on the type. Thus, most electrical measuring tasks can be solved with just a single module. There is a choice of different connection types: The ELM3704-0001 with its high-quality LEMO connectors is mainly designed for laboratory use, where sensor configurations are changed on a daily basis, but a stable and reliable plug connection is nevertheless required. The 6-pin version with push-in (ELM3704-0000/ELM3702-0000) on the other hand is ideal for industrial use where a plug is unplugged less frequently for maintenance purposes and fast wiring is much more important.

ELM3704-0000 | EtherCAT Terminal, 4-channel analog input, multi-function, 24 bit, 10 ksps

The EtherCAT Terminals from the ELM series were developed in order to enable the high-quality measurement of common electrical signals in the industrial environment. Flexibly usable measurement modules are especially useful in laboratory and testing technology environments. Therefore the ELM370x multi-function modules feature an input circuit that can be set to over 30 different types of electrical connection via EtherCAT: from voltages of ±60 V to ±20 mV, thus supporting thermocouples and IEPE, a current of ±20 mA, a resistance measurement of 5 kΩ and thus also temperature RTDs (Pt100, etc.), measuring bridges and potentiometers, and all of this with a 2- to 6-wire connection, depending on the type. Thus, most electrical measuring tasks can be solved with just a single module. There is a choice of different connection types: The ELM3704-0001 with its high-quality LEMO connectors is mainly designed for laboratory use, where sensor configurations are changed on a daily basis, but a stable and reliable plug connection is nevertheless required. The 6-pin version with push-in (ELM3704-0000/ELM3702-0000) on the other hand is ideal for industrial use where a plug is unplugged less frequently for maintenance purposes and fast wiring is much more important.
