2. General description
2.1 Introduction
2.1.1 Introduction to M-Logic
The M-Logic is a small logic controller incorporated in the AGC controller. Even though it is a logic controller, it must not be confused
with a PLC. The M-Logic can be compared with a PLC limited in functionality and can only be used for uncomplicated tasks.
The M-Logic can carry out binary control functions only; there are no possibilities for analogue reading and/or control functions.
The M-Logic can be programmed from the free PC tool, DEIF Utility Software (USW version 3). The USW can be downloaded from
DEIFs web page: www.deif.com/software
M-Logic setting is done in command lines. There are 40 lines, and each line contains three events, two operators and one output
with a possibility to make a time delay.
If two operators are not enough, a number of virtual events can be used to pass the control on to another line and carry on there.
This makes it possible to build larger event-based controls.
Application note 4189341276B EN Page 7 of 50

3. Configuration
3.1 Starting
3.1.1 Starting the M-Logic
Open the Utility Software and select the M-Logic & AOP button in the left menu.
Click the Read icon to load the M-Logic from the controller. The following screen appears:
3.1.2 Read/write
When the M-Logic screen is shown, the M-Logic toolbar appears at the top of the screen. The toolbar has two buttons which are
used to write and read the M-Logic configuration to and from the controller:
Press this button to read all M-Logic settings from the controller to the USW.
Press this button to write the M-Logic settings from the USW to the controller.
The M-Logic configuration can also be saved/opened to/from a file using the default save/open buttons.
Application note 4189341276B EN Page 8 of 50

3.1.3 Save/open
Press this button to save the M-Logic configuration to a file (part of the general configuration file “.USW”).
Press this button to open a previously saved M-Logic file.
3.2 Basic functions
3.2.1 Basic functions
The M-Logic consists of a number of lines, Logic 1, Logic 2 and so on. Each of these lines have:
• Three event settings
• Two operator settings
• One enable tick box
• One output setting
The Logic line can be collapsed or expanded with the button (1). When collapsed, the Item description (2) is still visible. The Item
description is stored in the .usw file, but not in the product itself.
Application note 4189341276B EN Page 9 of 50

3.2.2 Event settings
Events A, B and C are used to trigger the logic. For each event, the function NOT can be
selected to get an inverted function.
The event groups in the Events window depend on the controller type and its options.
Each event group contains a number of events. See the List of events chapter for
details.
3.2.3 Operators
Two operators are available:
• OR (any operator activates the function output)
• AND (all activated operators must have status ON to activate the function output)
3.2.4 Enable this rule
Select this tick box to activate the logic line.
Application note 4189341276B EN Page 10 of 50

3.2.5 Output settings
The output defines the reaction from the system, when the function is activated. A delay
time can be set for a function (no delay, if set to 0 s).
The groups in the Output window depend on the controller type and its options. Each
group contains a number of outputs. See the List of outputs chapter for details.
NOTE If a relay output is chosen, this relay must be configured as a limit relay
output in I/O setup or in the parameter list.
3.3 Definitions
TRUE state
A TRUE state of an input/event will be detected, if the condition defined in the input event is met. For example:
• Digital input is TRUE when activated (12/24V DC applied).
• Alarm condition is TRUE when the alarm is present.
• Mode condition is TRUE when the mode is selected.
FALSE state
A FALSE state of an input event will be detected, if the condition defined in the input event is not met. For example:
• Digital input is FALSE when deactivated (12/24V DC not applied).
• Alarm condition is FALSE when the alarm is not present.
• Mode condition is FALSE when the mode is not selected.
3.4 Examples
By using the events, rules can be made for the use of the M-Logic.
3.4.1 Virtual events
Virtual events are used to expand the number of events in a logic sequence. For example, the output of Logic 1 can be used to
continue the sequence in Logic 2.
Application note 4189341276B EN Page 11 of 50

• The Logic 1 output is set to Virtual Event 1.
• The Event A in Logic 2 is Virtual Event 1.
This gives a total of five events that can be used in this logic sequence (A + B + C in Logic 1 and B + C in Logic 2).
3.4.2 Set/reset function
If you use a single digital input to select AUTO/MANUAL, you need a SET/RESET function, since two digital inputs are normally
required for this.
In the following example, digital input 55 is used to switch between AUTO (input ON) and MANUAL (input OFF).
• First line: If input 55 = ON and AUTO = OFF (NOT Auto operation mode), then set AUTO mode command.
• Second line: If input 55 = OFF and MANUAL = OFF (NOT Manual operation), then set MANUAL mode command.
In M-Logic, it looks like this:
3.4.3 Configure an AOP LED
In this example, button 1 on a connected AOP (Additional Operator Panel) is used to activate Virtual Event 1. In the line AOP 1 (LED
1) is Virtual Event 1 configured to activate red LED 01 on the AOP to red blink.
Select an AOP with the tabs .
Configure an AOP button to Virtual Event 1 output as shown:
Configure line 1 in AOP 1 (LED 1) as shown:
Application note 4189341276B EN Page 12 of 50

Click on the Write button to save the AOP settings.
In the top menu, click on the AOP 1 button to open the virtual AOP display.
AOP LED colour priority
If an AOP LED has more than one output for selection of colour, the presented colour will follow this priority:
Priority Colour
1 Red flashing
2 Red
3 Yellow flashing
4 Yellow
5 Green flashing
6 Green
More information
See the document Option X Additional display and operator panel 4189340702 UK for more information about AOPs.
3.4.4 Controlling a relay output with a single AOP button
In this example, the relay can be replaced by any other output, and the AOP button can be replaced by e.g. a binary input.
• The button of the AOP-2 must be set to activate Virtual Event 1 (VE 1) (in this case).
• In Logic 1, the VE 1 will activate the relay output (21). At the same time, the relay output (21) will remain ON, unless Virtual
Event 2 (VE 2) is activated (AND NOT VE 2).
• In Logic 2, the VE 1 will activate VE 2 if the relay output (21) is ON (AND Relay output (21)).
Application note 4189341276B EN Page 13 of 50

The result is that the relay changes position every time the AOP button is activated.
3.4.5 Power up in a specific mode
In this example, the controller will always power up in manual mode. The timer in Logic 1 sets the output for 5 s, and this is used to
set manual mode in event 2. When the timer expires, you can freely select any mode since the virtual event 1 turns ON and the
Logic 2 says NOT virtual event 1.
3.4.6 Flip flop function
The flip flop function makes it easy for a pulse input to latch an output, for example a relay.
The Event selects a flip flop output (1 to 16), and the Output selects the output function:
• Flip flop set (1 to 16) = Change the flip flop output state to High.
• Flip flop reset (1 to 16) = Change the flip flop output state to Low.
• Flip flop toggle (1 to 16) = Shift the flip flop output state from Low to High or from High to Low.
Example
Application note 4189341276B EN Page 14 of 50

The example shows how flip flop set 1 could be configured to set relay 8:
• Logic 1: Flip flop output 1 is selected to set the relay output.
• Logic 2: Digital input 23 is used to trigger flip flop set 1 and thus sets the relay output active.
• Logic 3: Digital input 24 is used to deactivate the relay output by triggering flip flop reset 1.
• Logic 4: Digital input 25 is used to toggle the flip flop output state.
• Relay 8 must be set to M-Logic / Limit relay.
If reset and set are active at the same time, the flip flop will prioritise the reset command. The set or reset function may not be active
when the toggle function is used.
The flip flops are also accessible from Modbus.
