mAI085-MB Actuator Interface Technical Manual /1

1. Overview

The mAI085-MB Actuator Interface is an interface between the control room operator and a
network of Actuator Controllers. The interface is capable of controlling up to 100 actuators,
either on a single network of up to 31 controllers or through a series of network drops utilizing
RS485 repeaters. The interface allows for the pre-setting of setpoints for each of the actuators.
An open key opens all of the actuators to their preset setpoints. A close key closes all of the
actuators. A clear pushbutton sets all of the actuator setpoints to zero (fully closed).

The interface has optional features that allow the control of a conveying system. Timers are
provided which can delay the start of the actuator opening to allow a conveying system to start.
A second timer allows the conveying system to purge after closing all of the actuators.
Individual timers for each actuator allow for the distance between conveying system entry
points. The interface will open and close each actuator in sequence to provide superior
blending.

The interface communicates to the actuator controllers using the Modbus RS485 RTU protocol.

A Modbus RS232 RTU communications interface is provided for connection to a host computer
or PLC. The status information from all 100 actuators is available to the host computer or PLC
over this Modbus network. In addition, the interfaces front panel operators and enunciators are
mimicked over this network.

To facilitate configuration of the interface and the attached actuators a menu driven setup
system is provided. A table of parameters is saved for each actuator. The system allows the
retrieval and downloading of actuator parameters individually or for the entire network. A facility
is provided to backup the configuration to a TAB delimited file suitable for editing using Excel.

The interface can accommodate up to 100 actuator controllers if RS485 repeaters are used. A
typical repeater is the Phoenix Contact Part No. 2744429 optical isolated repeater. Up to 30
controllers can be on a single network segment (31 for the end of line). Using repeaters, a
linear network as shown above, or various forms of star or tee networks can be deployed as
required. The start of a branch on either a star or tee network must always begin with a
repeater.

A network expansion RS232 port is also provided. This port can connect directly to repeaters or
fiber-optic cable drivers. Controllers can be connected to both the standard RS485 port and the
expansion RS232 port. The port is designated J1 and is a female DB9 connector. It is wired
DTE.

4. Using the Interface

The controller has an easy to use keyboard for selecting and controlling the connected
actuators.

4.1 Selecting an Actuator Controller

Use the upper up or down keys to select the actuator. The right keys move between the
actuator one at a time. The left keys skip actuators at a time. The upper display indicates
which actuator is selected. The SCAN key allows the viewing of all connected actuators at one
second intervals. Pressing the SCAN key or any of the upper up/down keys can cancel scan.

4.2 Changing a Setpoint

The lower up/down keys change the setpoint for the selected actuator. The first press of any of
the up or down keys switches the lower display to the setpoint mode and the SV lamp will
illuminate. The right keys change the setpoint by 1. The left keys change the setpoint by 10.
The setpoint will not be saved and sent to the actuator until the SET key is pressed. If the SET
key is not pressed within 10 seconds, the display reverts to PV mode and the new setpoint is
discarded.

…Caution…

If it is required that all the actuators respond simultaneously to the

new setpoints, then first insure that the interface is in close mode

before making any changes to the setpoints.

The command to move the actuator is only sent when a setpoint has changed or the operating
mode is changed from closed to open. Pressing the SET key with the same setpoint value as
the previous move will not start a move operation.

4.3 Opening the Actuators

Pressing the OPEN key opens all actuators with a setpoint above 0. The OPEN indicator light
will illuminate. The STATUS display will indicate the status of the current open operation for the
selected actuator.

4.4 Closing the Actuators

Pressing the CLOSE key closes all actuators to a setpoint of 0. The CLOSE indicator light will
illuminate. The STATUS display will indicate the status of the current close operation for the
selected actuator.

5. Configuration

The mAI085-MB Actuator Interface is configured using a menu driven interface. The operator
keyboard changes function during configuration. This section will describe the configuration of
the interface. The description will first define the keyboard functions, then describe the
configuration menus used.

5.1 Overview of System Configuration

Each actuator connected to the Interface has parameters that control its operation. These
parameters are stored in non-volatile memory at each actuator. These parameters can be
modified using the keyboard of the Interface. The Interface can also store in its internal non­volatile memory, a copy of the parameters from each actuator.

The following table defines the steps used to set the actuator parameters and calibrate each
actuator controller.

5.3 Configuration Menus

There are four level of menus within the configuration system. The keyboard operation remains
the same for all of the menus. Menu items are selected using the upper right arrow keys. The
SCAN key is used to move back one level in the menu tree. To exit configuration the SCAN
key is pressed from the Main Menu.

There are 2 typical responses to a menu item. The first is a Yes/No response. The lower right
keys select YES (up arrow) and no (down arrow). The second is to modify the value displayed
by the menu item. The lower arrow keys serve 2 functions when modifying values. The left
arrow keys positions the flashing cursor to the digit to be modified. The right arrow keys
increase or decrease the value.

Any changes made to the selected items are immediate. The interface has non-volatile storage
for the system parameters. A modification to the parameters using the menus does not update
this non-volatile storage directly. Be sure to backup any changes using the SAv function from
the Main Menu before removing power from the interface. Each time power is cycled, the
interface restores the saved values from non-volatile memory. Any changes made will be lost if
power is cycled before a SAv operation has been completed.

of the actuator controllers. Additional menu items allow the recall and saving of the
parameters from the field device on an individual controller basis.

Provision is made to create a template from a specific controller. This template can then be
used to preset any additional controllers. Using the template/copy system can help speed
up the configuration process.

5.3.5 Factory Values Menu

The Interface can be configured to a range of factory preset values. The menu items allow
the selection of the actuator controller model, speed of actuator operation and actuator
accuracy. When the save function from this menu is executed all of the controller ID’s will be
reset to A1 – A100 and all of the controllers except controller 1 will be made inactive.

If no selections are made for tyP, SPd or ACC then the values from controller 1 will be used
as defaults. If a SAv is executed without tyP, SPd or ACC being set, the settings for
controller 1 will be propagated to all of the remaining controllers, the controller ID’s will be
reset to A1 – A100 and all of the controllers except controller 1 will be made inactive.

There are two ways to execute a factory reload. The first is to utilize a preset factory table.
This table contains known working values for all of the parameters suitable for most
installations. To select the correct tables for the actuator controller you are using, first use
tyP, SPd and ACC to select the model of your controller, the running speed of the actuator
and the required position accuracy. The required configuration can then be saved using the
Sav function.

The second method of saving default values uses a template that can be preset with a
modified set of values based on an individual actuator controller. To use this function, first
setup and test an individual actuator controller. Once the operation of this controller has
been verified use the template function (tPL) in the controller menu (CtL) to load the
parameter template buffer. To save this template buffer to all of the remaining controllers, do
not select a type, speed or accuracy, instead proceed directly to Sav function. Once select
this function will save the template parameter values to the Interface’s parameter table for
all100 controllers.

Note these tables are not automatically sent to the actuator controllers. Use the global Snd
command to move the Interface’s parameter table to the active controllers.

6. The Input / Output System

The mAI085-MB Actuator Interface has 4 discrete inputs and 4 discrete outputs. Figure 2 and
Table 2 detail the physical connections to the discrete signals. Each of the signals is described
below:

Name Description

Input 1
Pin 1

Input 2
Pin 2

Input 3
Pin 3

Input 4
Pin 4

Output 1
Pins 1 & 2

Energizing this input will select Open mode and turn on the OPEN indicator on the
front panel. Only the positive edge of the input signal is recognized and the input
must be de-energized between operations. Once energized, this input does not
affect front panel operator function.

Energizing this input will select Close mode and turn on the CLOSE indicator on
the front panel. Only the positive edge of the input signal is recognized and the
input must be de-energized between operations. Once energized, this input does
not affect front panel operator function.

Energizing this input will clear all of the actuators setpoints. The clear will occur
immediately. Only the positive edge of the input signal is recognized and the input
must be de-energized between operations. Once energized, this input does not
affect front panel operator function.

Energizing this input forces all of the actuators closed immediately. The actuators
will remain closed regardless of the controller being in Open mode. Open/Close
mode is not affected by this input and the actuators will re-open when this input is
de-energized if the interface is in Open mode. Open/Close timers are ignored by
this input and the force close will override any timing function in progress.

This output can have 2 functions depending on the setting of the oPL timer. If the
oPL timer is set to 0, this output will energize whenever the interface is in Open
mode. The output remains energized until the mode is changed to Close. If a
value has been entered into the oPL timer, this output will energize for the length
of time set by the oPL time, each time the Open mode is selected. This form of
operation can be used as a start signal for a conveying system.

Output 2
Pins 3 & 4

This output can have several functions depending on the setting of the cPL and
cDL timers. If the cPL timer is set to 0, this output will energize whenever the
interface is in Close mode. The output remains energized until the mode is
changed to Open. If a value has been entered into the cPL timer, this output will
energize for the length of time set by the cPL time, each time the Close mode is
selected. This form of operation can be used as a stop signal for a conveying
system. The energizing of this output will be delayed if a value other than 0 is set
in the oDL timer. The oDL timer can be used to purge a conveying system after
all of the actuator gates have been closed using the Close mode.

7. Controlling Conveying Systems

The mAI085-MB Actuator Interface allows the direct control of simple conveying systems. The
interface has several timers that facilitate this control. These timers in conjunction with the
discrete output system control the conveying system. The following timers are used:

ID Description Menu

oPL

cPL

odL

cdL

odL

Provides a pulsed output from Output 1 to start a conveying system. If this
value is set to 0, Output 1 will remain on continuously whenever the OPEN
lamp is on. If a value is set in this timer the output will pulse on for the time
selected in seconds each time the OPEN lamp turns on.

Provides a pulsed output from Output 2 to stop a conveying system. If this
value is set to 0, Output 2 will remain on continuously whenever the CLOSE
lamp is on. If a value is set in this timer the output will pulse on for the time
selected in seconds each time the CLOSE lamp turns on. The operation of
the output will be delayed if a value is entered into the cdL timer.

Delays the opening of the actuators to allow the conveying system to fully
start. Output 1 will energize (or pulse if oPL is set) immediately upon the
OPEN lamp illuminating. The actuators will begin to open after this delay in
seconds. This timer starts immediately upon entering Open mode.

Delays the stopping of the conveying system until all of the gates are closed
and the system has been purged. This timer starts after the CLOSE lamp
illuminates and all of the gates have been issued close commands. Once
this timer expires, Output 2 will energize (or pulse if cPL is set).

This timer allows for the different location of each actuator along a conveying
system. Actuators near the start of the conveying system must open first,
with each successive actuator opening a short time latter. This ensures an
accurate blend of the material. Each actuator has a timer that delays the
opening after the primary delay odL has expired.

8. Using the Modbus Network Interface

The mAI085-MB incorporates a RTU Slave Mobus interface. This interface responds to only 3
Modbus slave commands. The commands are 3 - Read Holding Registers, 6 - Write One
Holding Register and 16 - Write Multiple Holding Registers. The Modbus protocol allows a
maximum of 125 Register Reads and 100 Register Writes in a single transaction. The following
tables provide the register assignments for the Modbus interface. The command register within
the interface mimics the operation of the front panel keys and discrete inputs.

8.1 The Modbus Serial Interface

The physical connection is by a RS-232 port. The unit has a DB9 female connector, wired as a
DCE device. A modem or pin to pin cable can be used to connect the unit to a standard DTE
port. The connector pin-out is:

Pin Function at DTE device

1 DCD - always +9VDC
2 TX - data from mAI085-MB
3 RX - data to the mAI085-MB
4 DTR - not used
5 Common
6 DSR - always +9VDC
7 RTS - not used
8 CTS - always +9VDC
9 RI - not used

The unit supports 8 bit, even, odd or no parity in RTU mode. A full range of baud rates from
300 -19200 are supported.

8.2 Register Assignments

8.2.1 Read Only Registers

Two registers are assigned to each addressed controller. The mAI085-MB can address up to
100 controllers, starting from address 1 to address 100. Each addressed controller
corresponds to the following register table:

Distributive Intelligence

CMC INDUSTRIAL ELECTRONICS LTD

mAI085-MB Actuator Interface Technical Manual /30

Register Function

40002 Controller 1 Process value
40003 Controller 1 Status

40006 Controller 3 Process value
40007 Controller 3 Status
~ ~
40200 Controller 100 Process value
40201 Controller 100 Status

The controller process value is a 12 bit unsigned integer. The process value will occupy bits 0 ­11 of the process value word. The factory set range of the process value will be from 0 - 100,
signifying 0 - 100%. The controller status word definition is as follows:

Bit Function

0 Input 1 (Force Close) , 1 = input lamp off
1 Input 2 (Closed Limit) , 1 = input lamp off
2 Input 3 (Open Limit) , 1 = input lamp off
3 Input 4 (not assigned), 1 = input lamp off
4 Seek in progress, 1 = seeking
5 Motor running, 1 = running
6 Motor direction, 1 = close
7 not used, always 0
8 Position fault, 1 = did not reach position
9 Over fault, always 0, not implement in mGP145
10 Idle Load fault, always 0 not implement in mGP145
11 Parameter fault, 1 = parameters corrupted
12 Firmware fault, 1 = controller failed
13 Bad command, 1 = last command invalid
14 Calibration mode, 1 = in calibration mode
15 Communications fault, 1 = no communications

Distributive Intelligence

CMC INDUSTRIAL ELECTRONICS LTD

mAI085-MB Actuator Interface Technical Manual /31

8.2.2 Read-Write Registers

Each controller has one register for the setpoint value. The setpoint value will occupy bits 0 ­11 of the setpoint value word. The factory set range of the setpoint value will be from 0 - 100,
signifying 0 - 100%. Writing a setpoint to the setpoint register will cause the actuator controller
to immediately position the actuator. The value in the setpoint register must change to initiate a
move. If the actuator faulted in the last attempted move, a different setpoint value will have to
be written to force a new move. The actuator will only move if the interface OPEN indicator is
on. Open mode can be selected by pressing the OPEN key. The interface can be configured to
start in open mode from the local menu and open mode can be forced over the Modbus
communications system through the interface command register.

40301 Controller 1 setpoint
40302 Controller 2 setpoint
40303 Controller 3 setpoint
~ ~
40400 Controller 100 setpoint

8.2.3 mAI085-MB Special Registers

In addition, two special registers have been assigned. These registers are for controlling the
mAI085-MB Actuator Interface. The function of these registers is as follows:

Register R or R/W Function

40001 R mAI085-MB status
