DVP Peripheral Series

Frequency Measurement Card

Instruction Sheet

WARNING

This frequency measurement card is a specific function card for DVP-EH PLC, please use this card with DVP-EH MPU.

Frequency measurement card is an OPEN TYPE without any mechnical shield. When installing this card, user is supposed to power off the MPU and take precaution against static (anti-static glove) to prevent the surface parts of the card from being damaged.

Do NOT connect the AC power line to any of the input/output terminals, or it will damage the PLC. Make sure all the wiring is correct before power on.

To enhance the anti-interference performance of product, please make sure terminal FG is properly grounded.

Frequency measurement card is only workable for the DVP-EH with the version greater than 1.1.

3.2 Operation mode:

There are 3 types of operation mode for the frequency measurement card. User can decide the operation mode by setting CR1. Detail information as follows:

Mode 1: Pulse Interval Length Measurement (CR1=K1) Measurement method of pulse interval:

Interval of rising-edge

Interval of falling-edge

Inputs of pulse interval measurement: F0, F1.

Time unit of pulse interval measurement: 50ns, 100ns.

Interrupt function: I180 will be executed after frequency measurement card detects rising edge or falling edge in F0 and F1. And bit 0 of CR9 will inform interrupt trigger by F0 while bit1 of CR9 by F1. For more information, please see section 6.1.

Input frequency range: 1Hz~1kHz.

Accuracy: ±0.01% (max.)

Mode 2: High-speed Counter (CR1=K2)

There are 3 types for mode 2 the high-speed counter. The maximum input frequency of Pulse/Direction can be up to 200kHz. Explanation as follows:

Pulse/Direction: F0 is pulse input point. F1 is the signal to control the count-up or count-down. Counting method is shown as diagram as follow:

	Value			F0			Value			F1
			Rising-edge		Falling-edge				Rising-edge		Falling-edge

F1		High	Count-down		Count-up	F0		High	Count-up		Count-down
		Low	Count-up		Count-down			Low	Count-down		Count-up

Mode 3: Pulse Number Capture (CR1=K3)

Input point: F0 is pulse input point. F1 is the signal to capture pulse number.

Following diagram show the count method of pulse number:

Pulse Captured Period

The calculation of the pulse numbers for F0 is based on the interval between two rising edge or falling edge of F1.

Interrupt function: when PLC set M1019 (flag of operation mode setting for frequency measurement card) and D1034 (flag of operation mode setting for frequency measurement card) to set up operation mode, I180 will be triggered based on the rising-edge or falling-edge of F1. If PLC has I180, it will execute I180.

Accuracy: ±1 pulse.

CONTROL REGISTER

INTRODUCTION

Thank you for choosing Delta DVP series product. The frequency measurement card (DVP-F2FR) is the function card with 2 external inputs that accept digital signals. By using FROM-TO instruction, PLC can read/write the data or parameter in the frequency measurement card.

There are 255 built-in CRs (Control Register) in DVP-F2FR with 16 bits for each register. DVP-EH MPU can control the function of DVP-F2FR by programming the CRs.
