Inovance TCP Data Collection Guide

Inovance TCP Data Collection Guide

1. Protocol Overview

  • Protocol Description: The Inovance TCP protocol is a communication method that allows direct TCP/IP network connection to Inovance PLCs (such as H3U, AM/AC series). It supports efficient data exchange by reading tags or register addresses directly via Ethernet without requiring additional serial-to-Ethernet converters.
  • Application Scenario: This protocol is widely used for connecting Inovance controllers to HMI, SCADA systems, or edge computing platforms like E2C Trinity to achieve real-time monitoring and data collection.
  • E2C Trinity Support: E2C Trinity acts as a client, connecting to the Inovance PLC via a standard Ethernet port to read registers or tags.

2. Prerequisites

  • Hardware Connection: Ensure the E2C Trinity gateway and the Inovance PLC are connected to the same LAN.
  • Network Parameters: Obtain the IP address and the communication port (default is usually 502 or a specific PLC port).
  • Device Parameters: Prepare the PLC register address table and ensure the PLC's communication port is enabled for external access.

3. Configuration Steps

Step 1: Create a Data Acquisition Device

  1. Log in to the E2C Trinity management interface and navigate to [Data Acquisition].


  1. Click "Add Device" and configure the following parameters:

Parameter Name Description Example
Name The name of the device. Inovance-PLC-01
Driver Select the communication driver; select "Inovance - TCP". Inovance - TCP
IP Address The IP address of the PLC. 192.168.0.5
Port The communication port. 502
Poll Interval The interval (in seconds) for data requests. 10
Description A description of the device. Main Production Line PLC
Collect Timeout The timeout limit (in milliseconds) for responses. 1000
Connect Timeout The timeout limit (in milliseconds) for establishing a connection. 10000

Step 2: Configure Tags

  1. Select the device in the device list.
  2. Click "Add" to configure individual data points.

Parameter Name Description Example
Name Custom name for the data point. Temperature_01
Tag Type Select: Device Tag or Virtual Tag. Device Tag
Address The register address in the PLC. 40001
Data Type The actual data type in the PLC. Int16
Read/Write Permission Access permission (Read Only or Read/Write). Read Only
Data Operation Mathematical processing (None, Offset/Scale, etc.). None
  1. After adding or modifying all tags, click the "Publish" button in the top right corner of the page to apply the configuration.

Common Troubleshooting (FAQ)

  • Issue: Device status displays "Offline" or connection fails?
  • Solution: Check the physical network connection, verify the IP address and port, and ensure the PLC's TCP service is active.
  • Issue: Device is connected, but tag value is null or status is abnormal (red)?
  • Solution: Verify the register address and data type, and check if the PLC register is accessible.
  • Issue: How to view logs?
  • Solution: Navigate to [Debug Logs] or [System Settings] -> [System Logs].

5. Appendix: Data Type Mapping

When configuring tags in E2C Trinity, use the following mapping:

E2C Trinity Data Type Length / Sign PLC Corresponding Type
bool 1 bit BOOL (bit)
ushort(uint16) 16 bit, Unsigned UINT, WORD
short(int16) 16 bit, Signed INT
uint(uint32) 32 bit, Unsigned UDINT, DWORD
int(int32) 32 bit, Signed DINT
float(float32) 32 bit, IEEE 754 REAL
string 1...n bytes STRING, ARRAY
