1.7 Installation
Please put (embed) TP70P into a control panel. Use the fasteners and the screws in the container in which
TP70P is packaged. Insert the fasteners into the slots on TP710P, and then tighten the screws. (The torque
applied to the screws should be 4.75 kg-cm. It can not exceed 4.75 kg-cm, otherwise the panel will be
destroyed. If the fasteners are not used correctly, Delta does not guarantee a degree of resistance to water.
Please see the figures below. The control panel should be watertight and dustproof, or meet corresponding
specifications (IP66/NEMA 4).
Please do not install TP70P in the following environments.
 Environments in which there are dust, oily smoke, metal powder, and corrosive or flammable gas
 High-temperature and humid environments
 Environments in which TP70P may be shocked and vibrated directly

4.
The torque applied to the screws on TP70P should be 1.90 kg-cm (1.65 in-lbs). Only copper leads which
can resist the heat above 60°C/75°C can be used.
Please connect 22 to 12 AWG single-core or twin-core cables to the power input connector on TP70P.
(Only copper leads which can resist the heat above 60°C/75°C can be used.) The torque applied to the
screws on the PLC in TP70P should be in the range of 5~8 kg-cm (4.3~6.9Ib-in).
Please do not wire the terminal . Input cables and output cables should not be put in the same cable tray.
When users tighten screws and wire terminals, they should prevent tiny metallic conductors from dropping
into TP70P. After the wiring of TP70P is complete, the users have to ensure that TP70P can radiate heat
normally.
1.8 Wiring
1.8.1 Wiring a Power Input Connector
The power supplied to TP70P is DC power. When users use TP70P, they have to note the following points.
 Please connect wires to the terminals +24V and 0V. The power supplied to TP70P should be in the range
of 20.4 V DC to 28.8 V DC. If the voltage of the power supplied to TP70P is less than 20.4 V DC, TP70P
will stop running, and output devices will be off.
 If a power cut is shorter than 10 milliseconds, TP70P will not stop running. If a power cut is long, or the
voltage of the power supplied to TP70P decreases, TP70P will stop running, and output devices will be off.
If power is restored after a power cut, TP70P will automatically resume running. (There are latching
auxiliary relays and retentive registers in TP70P. Users should use them carefully when they design a
program.)

Chapter 1 Introduction

The power supplied to TP70P is DC power. A Delta power supply module (DVPPS02/DVPPS05) can be
used to supply power to TP70P. In order to protect DVPPS02/DVPPS05, users need to have the protection

2.3 Example
After users install, wire and power up hardware, they can prepare to write programs. In order to make the users
have a specific target and a specific direction before they begin to write programs, the manual provides a
common example for the users. The complete procedure which starts with the creation of a new project and
ends with the downloading of the project to a PLC is described step by step.

Control
The communication between a PLC and a Delta VFD-M series AC motor drive is described here. Y
devices on TP70P are used to control the forward/backward rotation of the AC motor drive. RS-485
communication (COM3) is used to read/set the frequency of signals output by the VFD-M series AC motor
drive. If the AC motor drive breaks down, an alarm signal in the AC motor drive will be sent to TP70P.
Actions:
1. If the AC motor drive rotates forwards, its forward rotation indicator will be on, and the input which makes
the AC motor drive rotate backwards will be ineffective.
2. If the AC motor drive rotates backwards, its backward rotation indicator will be on, and the input which
makes the AC motor drive rotate forwards will be ineffective.
3. If stop control is input, the operation of the AC motor drive will stop, and its stop indicator will be on.
4. The users can input a frequency range. The frequency range that the users set should be between the
maximum operating frequency of the AC motor drive and the minimum operating frequency of the AC
motor drive.
5. If the AC motor drive sends an error code, the operation of the AC motor drive will stop.

If the users want to change the state of a device, they can right-click the device, and click an item on the
context menu which appears. In the figure below, M0 is set to ON.
Note: Set On and Set Off can not be used to change the state of a device corresponding to an actual I/O
device because the state of the actual I/O device immediately overwrites the value which is set. Force ON
and Force OFF can be used instead.

C h a p t e r 2 Wr i t i n g P r o g r a m s

Monitoring devices
It is sometimes inconvenient for users to search for devices in a logic program that the users test, and
change the values in the devices because the devices are in different sections of the logic program.
Besides, sometimes the purpose of modifying the values in devices in a program is not to debug the
program, but to test an external device. If the users want to change the values in devices in a program by
monitoring the program, they may not easily find the devices, and they need to have the program. To solve
these problems, the users can use a device monitoring table. If the users change the values in devices in a
program by means of a device monitoring table, they do not even need the program.
The users have to click
, and then double-click the device monitoring table which appears.
After the users type a device name and the number of devices, and click Input in the Device monitor
input window, devices will be brought into the device monitoring table.

Example: PLC communication uses an ASCII mode.
If the communication format that PLC communication uses is the ASCII communication protocol (9600, 7, E, 1),
the program code below must be added to the top of the program in the PLC. When the PLC runs during the
first program scan, it checks whether M1120 is ON. If M1120 is ON, the setting of COM2 will be changed
according to the value in D1120.
Example: PLC communication uses an RTU mode.
If the communication format that COM2 uses is the RTU communication protocol (9600, 8, E, 1), the program
below will be required.
Notes:
1. After the modification of the communication format that COM2 uses is complete, the communication format
that COM2 uses will not change if the PLC stops running.
2. After the modification of the communication format that COM2 uses is complete, the communication
protocol that COM2 uses will be the default communication protocol (9600, 7, E, 1) if the PLC is turned off
and then powered when it stops running.
3. If COM2 functions as a slave station, users only need to set a communication format. If COM2 functions as
a master station, a Modbus command will need to be sent by means of a communication instruction
(MODRD/MODWR/MODRW)
3.4 Using the Communication Port Supporting PLC
Communication as a Master Station
【Question】How to use the communication port supporting PLC communication as a master station?
【Answer】If the communication port supporting PLC communication is used as a master station connected to
another device, commands will need to be sent by means of the Modbus instructions in a PLC program. Please
refer to Chapter 4 in DVP-ES2/EX2/SS2/SA2/SX2/SE&TP Operation Manual for more information about the
communication ports on a PLC. (Users can download DVP-ES2/EX2/SS2/SA2/SX2/SE&TP Operation Manual
from the official website of Delta (http://www.delta.com.tw).)
