DVP04PT-S Platinum Temperature Sensors

Instruction Sheet

Please carefully read this instruction thoroughly prior to use the DVP04PT-S. In order to prevent electric shock, do not touch the terminals or conduct any maintenance while

PLC power is ON. conduct any internal electrical work on the PLC.

This is an OPEN-TYPE device and certified to meet IEC 61131-2 (UL 508) safety requirements

when installed in an enclosure.

The DVP04PT-S must be kept under the environment away from high temperatures, high humidity,

exceessive vibration, corrosive gases, liquids, airborne dust, and metallic particles.

Do not apply AC power to any of the input/output terminals, or it may damage the DVP04PT-S.

Make sure that the DVP04PT-S is properly grounded , to prevent any electromagnetic noise.

Use wires with resistance when connecting the platinum resistance thermister (RTD) to the PLC. Please keep the wires as short as possible when connecting RTD to PLC and keep power lead

as far away as possible from I/O wires to prevent noise interference.

2.1 Model Explanation and Peripherals

 Thank you for choosing DELTA DVP Series PLC. The DVP04PT-S allows the connection of four

platinum temperature sensors (PT100 3-WIRE 100Ω 3850 PPM/°C(DIN 43760 JIS C1604-1989)).

The PLC converts the sensors input to a 14-bit digital signal, which then be manipulated using TO

and FROM commands in the ladder logic program. There are 49 Controlled Registers (CR, each

 DVP04PT-S is able to share the information via RS-485 communication or by direct connect to

DVP-SS main processing unit. Power supply and main processing units are sold separately.

 DVP04PT-S displays both Centigrade and Fahrenheit. The input resolution for Centigrade is 0.1

degrees and for Fahrenheit is 0.18 degrees.

 LED display:

1. Upon power-up, the ERROR LED will light for 0.5 seconds the POWER LED will light continuously.

2. No errors: POWER LED on and ERROR LED off.

Low Voltage error (lower than 19.5V), ERROR LED will blink continuously till the power supply goes above 19.5V.

3. DVP04-PT connected to PLC MPU in series = RUN LED on MPU will be lit and A/D LED or D/A LED should blink.

4. After receiving the first RS-485 command, the A/D LED or D/A LED will blink.

5. If the input or output exceeds the upper or lower bounds, the ERROR LED will blink.

 DVP-series PLC uses this command to write data to Controlled Registers of special

modules.



: When assign bit operand, K1~K4 are used for 16-bit and K5~K8 are used

for 32-bit.

 Using 32-bit command DTO. The program will write D11 and D10 to CR#3 and

CR#2 of special module#0. DTO allows only one group data to be written at one time when n=1.

 Command is executed when X0=ON. Nothing happen if X0=OFF, the stored data

will have no change.

 The rules for adding multiple special modules to a Main Processing Unit:

 m1: The maximum number of special modules attached to an MPU is 8. The

module closest to the MPU is 0 and the furthest module to the MPU is 7.

 m2: The number of Controlled Registers (CR) built in is 49. (#0~#48).  FROM/TO command read/write one CR at a time, while DFROM/DTO

command read/write two CR at a time. Example below:

 In ES series models, flag M1083 is not provided. When FROM/TO command is

executed, all interrupts (including external or internal interrupt subroutines) will be disabled. All interrupts will be executed after FROM/TO command is completed. Besides, FROM/TO command also can be executed in the interrupt subroutine.

 The function of the flag M1083 (FROM/TO mode exchange) provided in EP/EH

series models:

1. When M1083=Off, all interrupts (including external or internal interrupt subroutines) will be disabled when FROM/TO command is executed. The Interrupts will resumed after FROM/TO command complete. Please be advised FROM/TO command can be executed in the interrupt subroutine.

2. When M1083=On, if an interrupt enable occurs while FROM/TO command are executing, the interrupt FROM/TO command will be blocked till the requested interrupt finish. Unlike M1080 off situation, FROM/TO command cannot be executed in the interrupt subroutine.
