40032: DIGITAL INPUTS

This register contains the status of all digital inputs (0 = OFF; 1 = ON). In addition to using this register, it is also possible to read

each input using Modbus coil functions and the appropriate addresses from the "Coil Addresses" table.

40033: DIGITAL INPUTS RISE LATCH

Each bit of this register latches high (1) on a rising edge of its corresponding input. Once the latch is set, it must be cleared by writing

a 0 to the latch bit before it will register another rising edge transition. In addition to using this register, it is also possible to read and

write each bit using Modbus coil functions and the appropriate addresses from the "Coil Addresses" table.

Latch

40034: DIGITAL INPUTS FALL LATCH

Each bit of this register latches high (1) on a falling edge of its corresponding input. Once the latch is set, it must be cleared by

writing a 0 to the latch bit before it will register another falling edge transition. In addition to using this register, it is also possible to

read and write each bit using Modbus coil functions and the appropriate addresses from the "Coil Addresses" table.

40035: FREQUENCY DIGITAL INPUT 0

40036: FREQUENCY DIGITAL INPUT 1

40037: FREQUENCY DIGITAL INPUT 2

40038: FREQUENCY DIGITAL INPUT 3

These registers contain the frequency of pulses occurring on digital input channels 0–3, respectively. The value is in 16-bit unsigned

integer format, with units of hundredths of Hertz (i.e., Hertz with an implied two decimal places). The maximum measurable value

of frequency is 300.00 Hz.

40039–40040: 32-BIT COUNTER DIGITAL INPUT 0

40041–40042: 32-BIT COUNTER DIGITAL INPUT 1

40043–40044: 32-BIT COUNTER DIGITAL INPUT 2

40045–40046: 32-BIT COUNTER DIGITAL INPUT 3

Each of these pairs of registers shows the value of a 32-bit counter that increments at each rising edge of its respective input channel.

The counter values are stored as unsigned 32-bit integers, using two registers each.

At power-on of the device, the value of each counter is set to 0. The value can be reset to 0 by writing to the registers.
