Operation
The following pages describe how to operate the SRCM using the touch-screen interface.
The screen has two basic functions. The primary mode of operation displays the Home
screen, which shows the end-user pressure values, messages, text, and other data intended
for visual pressure verication in the facility. The second mode of operation is the Administrative Menu screen, which permits setup, conguration, and changes to how the
SRCM operates. After changes have been performed on the Menu screen, functions are
saved and operation returns to the Home screen. Note: If there is no user interaction with
the touch screen for more than 1 minute, the screen will automatically return to the Home
Screen. Many administrative settings can be written over the BACnet MS/TP network.

Home Screen
The default screen now has 2 possible modes. If the user wants to display other room
variables in addition to Pressure they can switch to the alternate home screen that shows
up to 4 parameters per room. These Parameters can be Pressure, Temperature, Humidity,
and user-dened (ex: CO2). The User switches modes by selecting slider on/slider off on
the bottom of the administrative menu.
The Home screen is the normal continuous operating mode of the SRCM. The Home
screen shows a Condition Banner on the left one-third of the screen, and Operating Conditions on the right two-thirds of the screen. There are two possible home screens, one
with a pressure only display with a slider bar representing the room pressure with respect
to the alarm setpoints. The alternate home screen can be used when there are multiple
parameters being measured in addition to pressure, such as temperature, humidity and a
user-dened option.

Condition Banner
The Condition Banner is the left 1/3rd portion of the screen that can be congured
by the end-user or facility manager to display a message to staff on the oor. The
Condition Banner can be Green, Yellow, Red or Blue, depending on the message
desired outside the pressurized space. The Condition Banner is set up in the Setup
Display-Condition Banner tab of the Administrative menu. There is also the op-
tion to display the Condition Banner in full screen.
The Condition Banner will change to red in alarm state regardless of the current
conguration. The banner may be changed manually, as required, by pressing the
touch-screen anywhere within the banner color region.

Operation
Once the messages of each of the four Condition Banners are dened in the Menu
section, the user can cycle through all four conditions by simply touching anywhere
on the left one-third of the screen. If passwords are enabled, the user will be prompted
to enter their password before proceeding. Each of the four colored screens can have
a unique message dened. See Section: Setup Display, page 11, for instructions on
how to setup the Condition Banner.
Alarms Cause
Condition Banner to
Turn Red
When the alarm occurs the Condition Banner will behave as follows:
1. Condition Banner will turn Red and Blink, irrespective of the color mode selected
by the user. User congured color mode: “Alarm Blink” & “Blink in Red” in the
Setup Display screen will remain same. The operation eld which displays the alarm
state of the system will also blink. When the system returns to normal user congured
settings will be retained.
2. The Message text on the bottom of the Condition Banner and User dened text on
top of the Condition Banner will be displayed as “ALARM” temporarily.
The Condition Banner can be congured so that any of the Condition Banner colors
can be set to blink when that condition occurs. For example if an alarm occurs, Red
color can be made to blink. Similarly, the yellow warning, green, and blue modes can
also be set to blink.
Condition Banner
Functions
The Condition Banner conguration on the Display screen will have 3 options: Active, Standby, and No Action for all four colors (Red, Yellow, Green, and Blue).
• When Active is selected, the Occupancy Status object of the SRCM will be active.
• When STANDBY is selected, then the unit shall be put into STANDBY mode (No
alarms will be generated) when the corresponding color condition is selected
• The No Action mode will do nothing other than to display the Condition Banner
screen that has been associated with the No Action mode.

The PRESSURE indication shows the intended direction of airow for the space.
POSITIVE for airow out of the space, NEGATIVE for airow into the space,
NEUTRAL for airow conditions that may vary, and STANDBY for use when there
is no need to verify the direction of airow (alarms are disabled).
The OPERATION indication shows whether the pressurized space is within normal
operating parameters (within alarm thresholds), or whether there is an alarm or warning condition. If operation is within alarm thresholds, a green NORMAL indication is shown. If operation is near either high or low alarm threshold limits, a yellow
WARNING indication is shown.
If operation is at or beyond high or low threshold limits, a red ALARM indication is
shown. If Audible Alarming is Enabled, a piezo buzzer will sound and a SILENCE
menu button will appear. Pressing the SILENCE button will shut off the alarm for
the period of time dened in the alarm conguration. Alarm operation can be congured to blink or sound an audible signal. See Section, Alarm Setup, page 15, for more
about setting up ALARM and WARNING conditions.
In addition to the pressure indication, OPERATION also displays whether a door
is open. If a door switch is congured, an open door contact will display a yellow
DOOR indication.

Pressure Value
A black banner displays the actual pressure reading from the space, in either inches
of Water Column (“ WC) or Pascals (Pa). The resolution of display can vary, depending on desired conguration; either 2, 3, or 4 signicant digits. The accuracy of
measurement remains the same regardless of the number of digits chosen.

Active and Standby
Modes
By pressing the touch-screen directly on the word POSITIVE (or NEGATIVE,
NEUTRAL, or STANDBY), the user is able to change the condition of the
room between ACTIVE and STANDBY modes. A pop-up menu appears to enable selection. If passwords are enabled, the user must rst enter a password to
proceed with the change.
In ACTIVE mode, the full function of the SRCM is active. In STANDBY
mode, the SRCM will perform all functions except that alarming will be dis-
abled (both audible and visual alarms). The STANDBY mode is designed to
put the SRCM into a mode where room pressurization is not critical, such as
cleaning, patient transfer, or longer-term unoccupied status. Note that this op-
eration can be password protected so that only an Operator or a Supervisor can
make this change. Passwords are set up in Setup Display Advanced tab.
10
Menu Screens
Pressing the MENU button on the Home screen brings up the Administrative Menu. If
passwords are enabled, the user is required to enter the correct password before being
authorized to make changes. From the Administrative Menu, the user can set all op-
erating parameters of the SRCM. This includes initial setup, commissioning, calibration, Network setup, customizing the displays, and warning and alarm parameters. The
menu structure is setup in such a way that the user can setup the unit by starting with
the left column and working down, moving to the next column and working down until
all setups have been made.

Setup Unit
The SRCM can take as input, the signal from two separate pressure transducers as well
as temperature, humidity, and user dened (ex. CO2) inputs for up to two rooms. These
are congured for either Primary Room or Secondary Room (an anteroom is an example
of a secondary room). When two transducers are used, the Home screen display of the
SRCM can toggle between each space to indicate the status of each room momentarily
cycling from one to the other. Alternatively, the display can be locked on either of the
two rooms.
*If Ch1 is selected for the Primary room, it will not be an available option for the Secondary room.

It may be necessary to change settings to match the sensor being used. OnBoard is the
default, which uses the sensor manufactured on-board the unit. Alternatively, an external sensor (also known as “external transducer” such as a Setra 264 or Setra 267) may
be used. If an external sensor is used, change this selection to ADC Ch1 (Analog Input
1) or ADC Ch-2 (Analog Input 2). The FS output and range of the external sensor will
need to be entered. If the OnBoard Sensor is selected, a box is shown displaying the
pressure range and engineering unit.
It may be necessary to change settings to match sensor being used, if there is one pres-
ent. There is no specic sensor listed at the default. An external sensor (Setra 264 or
Setra 267) may be used for the secondary room, or anteroom. If an external sensor is
used, change this selection to ADC Ch1 or ADC Ch2, which use Analog Input 1 or
Analog Input 2, respectively. The FS output and range of the external sensor will need
to be entered.
12
Room Parameters
The SRCM can display up to four (4) parameters for each of 2 rooms. The parameters can be Pressure, Temperature, Humidity, and the fourth user dened
(Ex., CO2). Start with the Primary Room and set up the Parameters to be monitored and displayed on the default or home screen. As Parameters and inputs
are selected further selection of parameters and inputs will become self limiting
(Ex., If Temperature is selected in Parameter 2, it is not available for selection
in Parameter 3 or 4.)
Start with Parameter 1, this is the Room Pressure. Select the Input Source as
OnBoard, ADC-Ch1 or ADC-CH-2.
Parameter 2, Select None, Temperature, or Humidity. Temperature is suggest-
ed. Select Source as ADC-Ch1, ADC-Ch2, or BACnet.
Parameter 3, Select None, Temperature or Humidity. Humidity is suggested.
Select Source as ADC-Ch1, ADC-Ch2, or BACnet.
Parameter 4 Select None, User Dened.

Sensor Range
On the display, touch the label box and using the data entry keypad, input the
Room Label for the Primary Room. This will be displayed at the top of the default screen to identify the room that the parameters refer to. Use the Primary/
Secondary Room radio buttons to select the secondary room (generally an
anteroom) and label that room as desired.
This Analog Output (AO) is used to communicate the value of the differential
pressure of the Primary Room to an external source such as a Building Man-
agement System (BMS). The value is scaled as either 4-20 mA, 0-5 VDC, or
0-10 VDC, selectable. A normalized pressure value is generated once every
100 milliseconds. The analog output is only available for the Primary room.
Units of measurement to show on the Home screen are selectable as either
inches of Water Column ("WC) or Pascals (Pa). The units are factory calibrated as "WC, but if the unit is changed to Pa, the rang will be change to
Pascals (Pa). This is selected from the Parameter 1 tab as it is associated with
the primary room pressure.
The SRCM is manufactured with an on-board differential pressure transducer.
This transducer is manufactured to specications for xed minimum and
maximum pressure measurement, known as the full-scale range of the transducer. When the on-board transducer is used exclusively, these values cannot
change. Alarm setpoints cannot be set above the positive value or below the
negative value. If a wider or narrower sensor range is required for the project,
an external pressure transducer such as a Setra 264 or Setra 267 may be chosen
to match the requirements. See more above under Primary Room or Secondary
Room.
If an external transducer is used, the full-scale values and other parameters
need to be congured into the SRCM so the unit understands the scale of measurement being received on the inputs Analog CH1 or Analog CH2.
13
Analog Inputs
The SRCM has 2 Analog Input Channels (ADC-CH1 and ADC-CH2)
Note: If a 4-20 mA transmitter is used as an analog input then a 250 ohm resistor
must be eld installed and this will be translated into a 1-5 VDC input at the input
terminals.
This takes an analog input from any transducer or transmitter: pressure, temperature
or humidity. If an external transducer is used, the full scale values and parameters
need to be congured into the SRCM so the unit understands the scale of measurement being received on inputs ADC CH-1 or ADC CH-2.
The following is an example using a pressure transducer to measure secondary room
pressures. This is showing a pressure transducer with a range of ±1"WC and output
of 4-20 mA over that range.
If selecting Analog Ch1 or Analog Ch2 for
either Primary of Secondary Room, enter
full-scale (FS) range that matches the transducer being used
Also enter voltage or milliampere range
that matches the transducer being used
The following is an example using a temperature sensor to measure primary room
temperature. This is showing a temperature range of ±50°C and output of 1-10 VDC
over that range.
Select desired units of measure to display on the Home
screen, either “WC or Pa. The unit of measure for the external transducer must be selected before entering range and
output of the unit. After entering all data the units may be
changed and the range will scale accordingly.
14
The following is an example using a humidity sensor to measure primary room
relative humidity. The range is 0-98 %RH with a 0-10 VDC output.

When nished making changes, press Save & Exit to store
the modications. Or press Exit to discard changes and return
to the previous screen
This function is used to improve the stability of the pressure value displayed
on the Home screen, so signicant digits do not change rapidly. It is used
more often in environments where the user requires higher display resolution
(4 digits) but the ambient pressure is unstable. By increasing the number, the
effective number of measured data points is increased and a weighted average is developed. Input the number in tenths of a second for the response time
of the display to a pressure change. There is no ratcheting of the display or
a deadband. The pressure change is very smooth. For example, entering 10
equates to the display reaching nal value in 1 second. Entering 2 equates to
nal value in 2 seconds.
Display Averaging does not affect the Analog Output response time, only the
apparent stability of the pressure display. Display Averaging also does not affect Alarm Thresholds or Alarm Delay.
What Pressure To
Display
This function denes what pressure value is shown on the Home screen under
normal operating conditions. This can be Primary Only, Secondary Only, or
Toggle, depending on what room is most important for visual pressure veri-
cation.
If this is set to Primary Only, then the Home screen will show the pressure
value read by the primary pressure transducer (either on-board, or the alternate primary transducer congured from a separate transducer, if one is used).
If a secondary transducer is in use, and an alarm condition occurs in the secondary room, the display will toggle and remain on the secondary room and
pressure value as long as the alarm condition is present in that space.
17
If this is set to Secondary Only, then the Home screen will show the pressure value read by the secondary pressure transducer (anteroom for ex-
ample). In this case, if an alarm condition occurs in the primary room, the
display will toggle and remain on the primary room and pressure value as
long as the alarm condition is present in that space. If no Secondary Room
is congured on the Setup Unit screen, attempts to choose Secondary Only
will result in the error “Secondary room source is NONE.”
If the function is set to Toggle, then the Home screen will show the pressure value for both rooms, alternating back and forth momentarily (approximately 10 seconds apart). If an alarm condition occurs in either room, the
display will toggle to the appropriate room and pressure value and remain
on that room as long as the alarm condition is present. If both rooms are in
alarm, then the alarm condition and pressure values will toggle.
Pressure Resolution
Supervisor and
Operator Passwords
This setting shows the number of digits after the decimal point
for the default screen pressure displays. This setting affects the
primary and secondary room settings.
The password function provides security against changed congurations by
unauthorized users. This is accomplished by using two levels of password
protection. These can be enabled or disabled.
The Operator level allows access to change between Active and Standby
room modes, but no other changes.
18
The Operator is the person that has day-to-day interaction with the monitor
to change operating modes from Active mode to Standby (where no alarms
are active). the operator can also respond to local audible and visual alarms.
This could be a Nurse or a Lab Technician. The SRCM was designed to
make interaction with the unit as easy as possible for the Operator. Changes to messages and to the room mode requires simply touching active areas
of the display. If Operator Password is enabled then a password will be
needed before the change can be made.
The Supervisor Level allows full access to all levels of the menu structure.
This mode is used during initial conguration and follow-on reconguration.
NOTE: The master Supervisor password is 351, and will work for any
condition where a user may need to reset passwords.
Condition Banner Tab-

Setup Alarm
The Setup Alarm screen permits authorized users (based on password level) to congure alarm behavior, such as the duration of alarms, methods of clearing the alarm
condition, and how alarms are acknowledged. It also sets the room mode to positive,
negative or neutral room.
Latch Alarm
Alarm Delay
If enabled, causes the display of red ALARM on the Home screen
to remain, even if room pressurization returns to NORMAL. Latch
Alarm enabled requires that an alarm event be acknowledged and that
the pressure returns to within the normal range. This is useful because
it forces recognition that an alarm event occurred. The alarm will still
be on even if the pressure returns to normal range. Only when the
alarm is acknowledged will alarming cease. When disabled, the alarm
will be silenced when the pressure returns to normal range without
requiring acknowledgement.
When a Latch Alarm occurs, the Home screen displays a RESET
button to the right of the Menu button. Press the RESET button to
acknowledge and reset the Latch Alarm condition.
Time between when the pressure went outside alarm setpoints and
when the unit goes into alarm mode. This is useful in preventing false
alarms. For example, if Alarm Delay is set to 20 seconds, the staff has
20 seconds to open a door, enter the room and close the door before
the alarm sounds (if audible alarms are enabled). Alarm Delay also
applies to alarms annunciated to a remote annunciator via the SRCM
Digital Output (hardware conguration).

Audible Alarm
Mute Time Out
Digital Input (DI)
Deadband
Buzzer Volume
Enables or disables the audible buzzer. Regardless of whether audible
alarming is enabled or disabled, the red ALARM condition will show
on the Home screen, annunciate to an SRAN, and propagate to a
congured Digital Output. If an alarm occurs and the audible alarm is
enabled, a new SILENCE button will appear on the Home screen so
that the operator can silence the audible alarm. The audible alarm is
silenced only for the period of time dened by Mute Time Out.
Sets the time (in seconds) that the alarm will remain silent after press-
ing the SILENCE button before the audible alarm resumes again.
This assumes that the room pressure condition is still outside the
normal setpoint operating limits. Mute Time Out can be set from 0 to
9998 seconds. Entering a value of 9999 will silence the audible alarm
“forever,” as long as a new alarm condition does not occur.
Used for monitoring the door status, open or closed. The DI is a Nor-
mally-Closed dry contact. A door jamb or valve pressure switch must
be wired to the terminals labeled DOOR in the rear of the unit. When
the door opens the contact will open, and this will show a yellow
DOOR Warning on the Home screen. The Door Alarm will suppress
alarms if they are generated at the same time that the door is open.
is adjustable from 0 to 10% and represents the region within the
setpoint range where yellow WARNING is displayed on the Home
screen to indicate that the pressure is near ALARM limits. If set to
0, no WARNING will occur, only ALARM when the pressure value
reaches setpoints. If set to any other value, WARNING will be dis-
played if the pressure value reaches that percentage of total pressure
setpoint range.
When the unit goes outside of the deadband range the alarm will oc-
cur. The alarm will remain until the pressure returns within the alarm
limit range (or acknowledged Latch alarm) minus the setpoint.
The buzzer volume can be adjusted from one to four, with four being
the highest sound level. The alarm buzzer is disabled using audible
Audible Alarm disable function.

Alarms Disabled when Door
Open & Buzzer for Door
Warning
The SRCM is able to congure the Room status to disable the Alarms when
Door is open. This function is used when there will be high trafc through
the area and the user wants to disable any alarms that are occurring as the
result of the door being open. The alarms will be re-enabled once the Door
is closed.
In the Alarm Setup screen, select the digital input choice to Door Alarm.
As shown in the screen below, the DOOR indication (to the right of
Operation) will be highlighted to indicate that the door is open but that
STANDBY (to the right of PRESSURE) will indicate that the room is in
STANDBY mode.
24
If the door opens when the unit is in alarm, unit will continue to operate in
alarm state instead of clearing the alarm.
Alarm Set Point
For each space, Primary Room or Secondary Room, this screen is used to dene the alarm
setpoints. When the room is then set to Positive, Neutral, or Negative, the setpoints and con-
ditions congured here are in effect for alarm and warning conditions.
Alarm Matrix
The SRCM has a great deal of exibility to dene alarm conditions. Alarms and warnings
can be congured for primary and secondary rooms, and for the door. Room display can
toggle between Primary and Secondary. The following table outlines what will occur in
terms of priority and display under normal and alarm conditions.

Calibration and
Self-Test
This page is used for calibration of the internal pressure transducer sensor
and testing operation of hardware circuitry. Calibration is only required for
highly accurate measurement needs such as those needed to comply with
federally mandated regulations. Calibration should only be performed by
qualied personnel.
1. Select Primary or Secondary room. When selected, the gray box to the
right will indicate if the calibration will be applied to the on-board sensor or
the external sensor (Analog Ch1 or Analog Ch2). The indicated pressure is
shown.
2. Calibration of the on-board sensor requires that the faceplate be removed
and the captive screw holding the display cover must be loosened (at the
bottom-center of the display bracket).
3. Lift the cover to expose the clear and red tubing connecting the on-board
sensor to the pressure ttings in the rear of the unit.
4. Remove the tubing from the high and low ports (red and clear tubing).
This disconnects the sensor from the room pressure.
5. After calibration, replace the red and clear tubing.

Pressing Zero Adjust button will bring up a “Is zero pressure
applied?” message. If yes, press OK. If the zero measure-
ment is within 10% of the factory zero measurement stored
in the unit, the zero value will be reset. Note: Zero Adjust
should only be performed after the unit has been operating
for 30 minutes in the installed location.
This requires the use of a Pressure Calibrator, such as a Setra
Model 869 or equivalent. Connect tubing from the Calibrator to the low and high ports identied near the PCBA
markings. Apply Full Range pressure, for example ± 0.1”
WC range, use 0.1” WC. When pressure reaches Full Range
pressure, press OK button. The output at Full Range must be
within 10% of the factory calibration to allow re-adjustment.
If the unit has been miscalibrated in the eld, the factory
zero and span settings can be restored.
The Buzzer, Relay and Internal Memory checksum can be
tested and veried.

USB
Conguration
Cloning
The SRCM has a USB port built in for the purpose of duplicating congurations
when multiple units are being setup with similar congurations. To use this function, a USB 2.0 thumb drive with 256 megabytes or larger must be used. The thumb
drive must have at least 100K or free memory available. The USB port should only
be accessed by qualied personnel.
Setra recommends the Kingston DataTraveler 112, 4GB (minimum) ash drive
along with the aid of a short mini-USB adapter cable from Tensility International
Corporation, P/N 10-00003. No PC is required.

To access the USB port, rst remove the faceplate cover and set it aside. The USB
port is located on the right side of the touch-screen display driver board, and is ac-
cessed by removing the security screw and ipping up the display housing. A miniA MICRO USB Host Mode OTG cable (from T& S Electronics, P/N: OTG-SBK6
or from SonoXY, P/N: USB_MIC-OTG) is required to connect a standard USB 2.0
compliant thumb-drive to the SRCM USB port.
To make use of the cloning feature, rst setup one SRCM with a conguration that
represents most other SRCM units that will be used during installation. Congure
the “master” unit with all parameters needed, including alarm thresholds, condition
banners, blinking operations, I/O conguration and so on. Make sure the Save &
Exit function is used to properly save your conguration. This “master” setup will
then be downloaded to the thumb drive and for use uploading to other units.
As soon as the thumb drive is connected to the SRCM it will be recognized and
bring up a Drive Connected menu.

• Select Conguration Write to transfer the master SRCM conguration from the
unit to the thumb drive.
• Select START to initiate the copy operation.
Remove the thumb drive and cable and move to the rst “slave” unit to be cong-
ured. With power applied to that unit, connect the thumb drive and cable. Select
Conguration Read and START to write the master conguration to the new slave
unit.
A Write Process Successful message will appear if the conguration has been
written to memory. Review the various Menu screens of the slave unit and sub-
sequent units to conrm the proper conguration is stored. In most cases the only
change that will be required to clone SRCM units is Primary and Secondary Room
labels that match the location of installation.

Updating Firmware
Note: Before updating rmware, perform USB Conguration Cloning. Refer
to USB Conguration Cloning on previous page.
The USB port can be used for upgrading the SRCM rmware in the eld.
To upgrade the rmware you must rst download the rmware for the latest versions of the hex le for the host controller, the USB hex le and the
BACnet hex le, these are EMS1009.hex, usb.hex and BACnet.hex. Place the
new les on the thumb drive. Plug in the USB adapter cable, shown on previous page, and the ash drive.
The SRCM will automatically detect the USB drive bringing up a window.
1. Press the Change button.
2. Scroll to the Upgrade Host Firmware screen shown here.
3. After the host rmware has been updated, change to the Upgrade

The Network Setup screen gives the option for the user to congure the
Network and other parameters which have to be read from the network.
BACnet conguration requires the user to congure the following parameters.
1. Baud Rate - User can select any one of the 4 standard Baud rates for
RS485 communication from 9600, 19200, 38400 and 76800 by using the
change button. Auto baud features is not supported.
2. MAC Address - User can enter Medium Access Control address specic
to this device by touching on this eld. The MAC address must be unique
across the network. Valid MS/TP MAC addresses are 0-127 for master devices and 0-254 for slave devices.
3. Device Instance - The Device instance number must be unique within a
BACnet internetwork to identify each device. Instance numbers are dened
as 22 bit long, in decimal instance number ranges from 0 to 4,194,303.
FFFFNDD is the network addressing scheme, here FFFF represents the Facility code. N is the number of the network in the building and DD ranges
from 0 to 99 to represent the individual device on the network.
32
4. APDU Timeout - Indicates the amount of time in milliseconds between retransmissions of the APDU requiring acknowledgement for which no acknowledge-
ment has been received. The default value for this property will be 3,000 ms and
max can be 65535.
Save and Exit to save settings or cancel to cancel setting changes.
Once this is complete disable the BACnet setup by moving the dip switch position

5. After the unit returns to the main menu screen, disconnect the power to the unit
and reconnect in order to boot up with the proper MAC address and Device In-
stance. The power can also be cycled by removing Jumper JP1 and then reconnecting.
Removing the jumper
causes power loss.
Re-insert the jumper to
restore power.
The unit can also be congured through the BACnet interface as well as through
the Touch Screen User Interface.
33
Event Log
The SRCM can be enabled with an audit trail of changes made to the congurations/
modes of the system by Supervisor and Operator. When the Supervisor / Operator
changes any conguration through the menu, the action is captured and stored in a
string covering the User prole Screen name where the parameter is changed. There
will be 5 such instances stored in non-volatile memory of the unit. Any power failure
in the unit will lose the data and it will be the responsibility of BMS system to log
these strings after polling from the SRCM unit through BACnet. The SRCM unit
will store these strings as different instances of Character String Object.
The value to which the parameter is changed will not be logged for parameters like
User Dened Condition Banner text, Room Label, Message Text, etc., which needs
more memory. Other parameters whose variables are enumerated, real and integer
will be logged until the value is changed.
The string length of each instance of conguration change will be 50 Bytes in the
data memory area of the controller.
