Abstract

This document describes using the Siemens S7-300/400 TCP/IP Master driver to communicate with a Siemens Logo! Basic module.

Products

Red Lion Controls CR1000 Human Machine Interface (HMI), CR3000 HMI, Data Acquisition (DA10, DA30), Data Station Plus, FlexEdge™ (DA50D, DA70D), G3 HMI, G3 Kadet HMI, Graphite® Controller, Graphite HMI, Modular Controller, and ProducTVity Station™ 

Use Case

Communicating with a Siemens Logo! module.

Introduction

Red Lion has not had the chance to test all of the Logo! modules, the mapping mentioned below are the ones that Red Lion or customers have verified with the modules that have been tested.

Crimson Communication Configuration

1. Navigate to the COmmunications section.

2. Click on Network (Crimson 3.x) or Ethernet (Crimson 2.0).

3. Configure the Ethernet port as required for the application.

4. Click on the first available Protocol under Network (or Ethernet).

5. Click the Pick button in the Driver Selection section.

6. Under Manufacturer, choose Siemens.

7. Under Driver, select S7-300/400 TCP/IP Master, as shown in Figure 1.

8. Click OK.

9. Click on the device below the protocol, PLC1 as shown in Figure 2.

10. Set the IP Address to the IP address of the Logo! module.

Crimson Tag Mapping

The following sections show how the addresses in the Logo! correspond to the addresses available in Crimson.  In the case of bits, the Red Lion address is listed as Byte.Bit. Figure 3 shows a Flag tag mapped to MB1.3 (M12 in the Logo!).

The following data is available for access from the Logo! modules that have been tested:

Input Bits

Logo! Red Lion
I1 IB0.0
I2 IB0.1
I3 IB0.2
I4 IB0.3
I5 IB0.4
I6 IB0.5
I7 IB0.6
I8 IB0.7

Output Bits

Logo! Red Lion
Q1 QB0.0
Q2 QB0.1
Q3 QB0.2
Q4 QB0.3

Analog Inputs and Outputs

Analog inputs and outputs will most likely be mapped to I or Q registers, respectively.  They are 16-bit values, so Numeric tags would need to be mapped with the Byte as Word data type.
