receiving register

In data exchange, DVPEN01-SL will execute Write (Æ) first before Read (Å).

Quantity: A slave is able to send and receive at the same time maximum 100 consecutive data.

f For data exchange, D register is parted into 2 sections, D0000 ~ D4095 and D4096 ~ D9999.

Please DO NOT use different sections for the consecutive sent and received data (start

address + number of data).

5. See “Application Examples Section 6.11” for more details.

5.6 RTU

Use the “RTU” function to conduct mapping between Delta’s network modules DVPEN01-SL and

RTU-EN01.Set up the mapping information first, and you will be able to use WPLSoft in DVPEN01-SL to save

and retrieve the mapped bit (M) and register (D) in order to operate the remote RTU-EN01.

 The settings

1. Enable Remote I/O Mapping:

Check the box to enable the remote I/O mapping. The mapping with remote RTU-EN01 will be

enabled according to the settings.

2. Communication Parameters:

Set up “Communication Timeout” (ms) and “Update Cycle” (ms) here.

3. PLC I/O Mapping:

Set up the start address of the mapped bit and analog register (RCR) of digital input (X) and

digital output (Y) on remoter RTU-EN01. The bit starts from M2000, and read/write register starts

from D2000/D3000. The software will automatically calculate the end address according to the

settings below.

4. Remote Device Mapping:

Check “Enable” and enter the remote RTU-EN01 ID (Slave ID), IP Address, number of digital

input points (RX), number of digital output points (RY), number of mapped read registers (Read)

and write register (Write).

DVPEN01-SL offers 4 slaves for mapping. Max. number of digital and analog points for mapping

1 2 ... 23 24 25 26 27 28 29 30 31 32 33 ... 57 58
