Introduction

Q.1: Name the four configuration sections for SoMachine Basic.

Properties, Configuration, Programming and Commissioning

Q.2: SoMachine Basic can be used to program which Machine Solutions logic controllers?

[Only the] M221 

Q.3: What are the two ways to connect to the Logic Controller for programming and commissioning?

USB or Ethernet (where fitted to the logic controller) 

M221 Hardware

Q.1: What voltage power supply can be used to power the M221?

24V DC 

Q.2: What is the maximum I/O supported by the M221?

144 

Q.3: The HE10 connector is fitted to which of the M221 Logic Controllers?

M221s with 32 I/O built in 

(TM221M32TK and TM221ME32TK) 

Programming a Simple Application

Q.1: Explain the following addresses.

Address	Int/Ext	Location	Data Type
%I0.4	External	Logic Controller	Bit
%MW2	Internal	Variable Memory	Word
%Q0.6	External	Logic Controller	Bit
%IW1.2	External	First Expansion Module	Word
%S6	Internal	System	Bit
%MF10	Internal	Variable Memory	Float
%KW2	Internal	Constant memory	Word
%SW100	Internal	System	Word

Q.2: Create an address for the following.

The second digital input of the logic controller

%I0.1 

An internal memory location that can be used to store the value 17.4 

%MW1 (The location is chosen to suit the application) 

System word 8 

%SW8 

The third output of the second expansion module (assuming that it is a digital output) 

%Q1.2 

The first input of the second digital output module 

This will depend on exactly where the expansion module is located as it could be in any position following the first. 

Q.3: Which languages are supported by SoMachine Basic?

Ladder and Instruction List. 

Q.4: What type of object is %SW1 and can you write to this object? 

A System Word that cannot be written. 

Q.5: What is a quick way to create multiple symbols? 

Export the symbol list and use Excel 

Q.6: How can an output be turned off when it has been turned on using a Set coil? 

Normally using a Reset Coil (but it can also be turned off if the object is programmed as a normal coil later in the program) 

Q.7: Which block can be used by the program to write values into objects?

The Operate Block. 

Getting it all Working

Q.1: Which LEDs should NOT be illuminated during normal operation? 

ERR, SD and BAT. 

Q.2: Is it possible to search for an object name? 

No. 

Q.3: What options are there for changing a value in an animation table? 

Change the value of an object or forcing. 

Taking it Further

Q.1: What file extension do template files have? 

.smbe 

Q.2: What type of IP addressing is supported by SoMachine Basic/M221? 

Static, DHCP and BootP 

Q.3: Which serial port protocols are supported by SoMachine Basic/M221? 

Modbus ASCII, Modbus RTU and ASCII 

Q.4: What can the M221 Real Time Clock be used for? 

To trigger events that need to happen at a certain time and/or on a certain day and for time-stamping events. 

Documenting the Application 

 Q.1: How do meaningful POU and Rung names help?

They can self-document the application meaning that the purpose of a rung can be seen without having to refer to other documentation. 

Q.2: Where can comments be added to the program? 

Comments can be added to each rung of the program. 

Q.3 What information can be stored in the Front Page? 

Information about the engineer and company that produced the application.
