Chapter 1 – generaL DeSCription
introDUCtion
Since 1988 MICRO‑AIDE has provided the rail signal industry with a broad range of event recording
devices and systems that vary in capacity, size and features. Our considerable expertise in this eld has
also been used to create a highly innovative product referred to as a Vital‑Processor Data Logger (i.e.,
VDL). The VDL is unique in its ability to gather and report event data by communicating directly with a
Programmable Logic Controller (PLC). The VDL does not require wired attachments to spare vital and/
or non‑vital relay points in order to report Digital Input events. Considerable material and labor‑related
expense can be avoided by using the VDL in place of a standalone Event Recorder. Additionally, a user
interested in gathering incident or maintenance data will no longer need to log onto the PLC. Instead,
critical data can be acquired by accessing the VDL which operates strictly as a passive, non‑vital moni‑
toring device.
The VDL can be used with an Ansaldo Microlok II and Siemens S7‑300 controller. The installed rmware
determines which PLC will be monitored. The hardware used by both versions is identical.
This User Manual describes the Siemens S7‑300 version of the VDL. The current version of the Microlok II
and S7‑300 rmware are available for free downloading from the following web page:
www.micro‑aide.com/support/downloads.htm. To be used with a VDL, the Siemens S7‑300 must be
equipped with the CP 340 Communications Processor option.
Like many devices, the VDL utilizes an internal real‑time clock for date and time stamping events.
Historically, these real‑time clocks have been susceptible to drift. Over the course of several months the
accumulated drift can exceed several minutes. This factor can greatly complicate incident investigation
and reporting. However, the VDL eliminates the problems introduced by clock inaccuracy once and for
all. The GPS Receiver option utilizes GPS technology to set the time and date. Alternatively, the Ethernet®
Port option allows the Data Logger to communicate with a LAN‑based time server. Time servers broad‑
cast time and date information using the SNTP protocol. The VDL is designed to support Unicast and
Multicast SNTP messaging. Any of these three methods provide for time stamping that is 100% accurate
and drift‑free without the need for any user intervention.
As a convenience to its user, the VDL can copy Event Records directly to a FAT‑32 formatted ash drive.
The USB Host Port is a standard feature of the Data Logger. Install a ash drive into the unit’s front panel
socket, press a few keypad buttons and in seconds Event Records from any time span are written as a
.txt le. The .txt le can then be read, e‑mailed or printed as required.
Every VDL comes equipped with a built‑in keypad and display screen located on the front panel. This
allows the user to effectively operate the Data Logger without additional peripheral devices. However,
each logger will support applications that require PC‑based storage of Event Records. The logger is
equipped with USB and serial Terminal Ports. It can also be equipped with an optional Ethernet Port.
Collectively they provide for increased exibility when interfacing with the logger. The USB Device and
Ethernet Ports provide high speed data transfer rates of 960 Kbps and 850 Kbps, respectively. A PC is then
used to retrieve, store and review Event Record data of interest to the user.
An optional 33,600 Baud internal modem can also be installed. It too allows the user to remotely access
and operate the Data Logger. A standard phone line connection allows the user to gather critical Event

VDL S7‑300 USer ManUaL

Records from any location, however distant. The modem can also be used to provide dial‑out alarm
reporting to a maintenance facility.
The VDL is also equipped with four general purpose Analog Inputs. The Analog Inputs can be used to
monitor both DC and AC voltages such as battery levels and commercial power voltages.
Eight Virtual Inputs allow the user to create Event Records based upon a specic logical association of
several Digital, Analog, Timer and other Virtual Inputs. The Virtual Input feature can be very useful in ana‑
lyzing failure conditions or in creating alarm indications. Tedious and confusing site‑specic proles are
not required when using the Virtual Input feature.
Sixteen Timer Inputs can be used to measure and report the elapsed time between any two events. As
an example, the duration of a bit transition, the time between two separate bit events or the occurrence
of an Analog Input event and a bit event can be reported. Additionally, separate High and Low Limit
Values can be assigned for each timer. An event occurrence that is too fast or slow when compared to
the Limit Values is identied in a Timer Input Event Record.
All MICRO‑AIDE rail signal products, including the VDL S7‑300, are designed to be easy to use and main‑
tain. Each design is based upon the premise that value and reliability start with attention to detail and a
concern for usability rather than needless complexity. Our goal in creating the VDL was to provide the
rail signal industry with an instrument maintainers and signal technicians will nd easy to operate long
after the Data Logger has been installed and set up.

This chapter describes how to properly unpack and install the VDL S7‑300 prior to operation. It is advis‑
able to perform the Initial Check‑Out Procedure before attempting to set up the Data Logger.
UnpaCKing
Each VDL is packed in a shipping carton that is properly sized for the device. Abundant packing materi‑
als are provided to minimize mechanical shock to the contents. Before opening the carton inspect it for
damage. Damage to the carton should be noted. Carefully remove the logger. It is advisable to save all
packing materials in the event the unit ever needs to be returned to MICRO‑AIDE.
Inspect the unit for visual damage. It should not be scratched, dented or deformed in any way. If it
appears the logger was damaged in shipment the responsible carrier should be notied immediately.
MICRO‑AIDE will assist the user in ling a claim in the event damage was sustained during shipment.
initiaL CheCK‑oUt proCeDUre
Before the VDL is installed at a signal facility it is recommended that an operational check of the logger
be performed. The following materials are required as a part of this procedure.
• 12 Vdc power source.
• Common hook‑up wire for power and testing inputs (12 to 22 AWG).
• Wire strippers and small, at‑head screwdriver.
• PC equipped with a communications program (e.g., HyperTerminal®) and either a USB port or serial
comm port set to operate at 38,400 Baud.
• Digital Voltmeter (DVM).
Perform each step in the sequence listed in the following. If a problem arises, refer to the sections entitled
“Diagnostic Testing” on page 76 and “Trouble‑Shooting Guide” on page 82. Elements common to
most installations are illustrated in Figure 1 on page 8 and Figure 2 on page 9.
1. With the power off, connect the power source positive and negative conductors to either pair of ter‑
minals labeled “B” and “N”, respectively. They are located at the right end of the logger’s top panel.
2. Connect the PC’s serial comm port to the DE‑9 male connector labeled “Terminal”. Use the cable
provided by MICRO‑AIDE or a DE‑9 to DE‑9 straight‑through cable. Figure 6 on page 87 illustrates

This concludes the Initial Check‑Out Procedure. This procedure may be used at any time to verify that
the VDL is operating properly. Power can now be removed from the logger. Connections to the PC
should also be removed.
In the event that a failure occurs during any part of this procedure a series of diagnostic tests should
be performed. Refer to the sections entitled “Diagnostic Testing” on page 76 and “Trouble‑Shooting
Guide” on page 82. Alternatively, the user may wish to contact MICRO‑AIDE customer service.
Instructions on how to proceed will be offered. “Material Return” and “Limited Warranty” policies are
described on the inside back cover of this manual.
inStaLLation proCeDUre
The following sections describe the recommended Installation Procedure. Figure 1 on page 8 and
Figure 2 on page 9 illustrate elements that are common to most installations. The illustrations also de‑
pict the location of each connector used in the installation.
LoCation
The location where the VDL is to be installed should comply with a few simple requirements. The ambient
temperature near the logger should be in the range from ‑40 ºC to 72 ºC.
MoUnting
The VDL can be mounted on top of a suitable shelf or secured to a back board. Each logger is equipped
with non‑slip, rubber feet. Precautions should, however, be taken to prevent the unit from dropping off
the edge of the shelf or desktop. The shelf mounting brackets provided with the unit can be used for this
purpose. To attach the shelf mounting brackets remove the four rubber feet. The provided screws and
threaded holes vacated by the rubber feet are used to install the brackets. If a PC is to be used it must
be properly secured.
Contact MICRO‑AIDE in the event 19″ rack mounting brackets are required. Refer to the section entitled
“Accessories” on page 89 for ordering details.
Site preparation
The equipment location must have access to a stable 9 to 36 Vdc power source. A pair of wires must be
run from the power source to the location where the logger will be mounted. The VDL wire ends must be
stripped approximately 1/4″. The stripped ends will be secured by tension clamp terminals located along
the top panel of the unit. One wire must be connected to the positive voltage of the power source
and the other wire must be attached to the return of the power source. The tension clamp terminals will
accept wire sizes as large as 12 AWG. The two wires must be properly secured to prevent damage. It is
preferable not to run the wires adjacent to electrical equipment such as motors that may generate large
electrical disturbances.
The serial comm port labeled “To Vital‑Processor” must be connected to the CP 340 Communication Port
of the Siemens S7‑300. Use the cable provided by MICRO‑AIDE or a DE‑9 to DE‑9 straight‑through cable.
Figure 6 on page 87 illustrates the proper wiring of the cable. The VDL must be mounted within six
cable feet of the vital‑processor.
The Analog Inputs also use a tension clamp style of detachable connector. Each wire should be tagged
with its circuit identity. Each input cable or wire bundle should be secured to prevent damage to the
connections at either end.
The VDL can be programmed to issue an alarm indication signal. A form C relay with normally closed
and normally open contacts is available at the connector alongside where power is attached to the
logger. The contacts are rated for 2 Adc at 24 Vdc and 1 Aac at 125 Vac. The relay can be used to con‑
trol an external light or warning device.

VDL S7‑300 USer ManUaL
12 Micro‑Aid e

The GPS Receiver option utilizes an external antenna. The bulkhead‑style antenna is designed to be
mounted outdoors on any surface less than 3/8″ in thickness. It requires a 1/2″ diameter hole to be drilled
through the mounting surface. The hole should be properly sealed. The antenna assembly also includes a
washer, nut and 16' cable.
peripheraL eqUipMent
If a PC is to be co‑located with the VDL an appropriate AC power source must be available. Additional
connections can be made as described in the following sections.
USb DeViCe port
If an on‑site PC is to be used MICRO‑AIDE recommends that the USB Device Port be connected to a USB
port of the PC. The USB Device Port will support data transfer rates of 960 Kbps. A standard USB Type A‑B
cable is used for this purpose. Table 14 on page 87 lists the bit transfer rates of each user‑accessible
port.
To use the logger’s USB Device Port the proper drivers must be installed in the PC. Appendix C de‑
scribes how to locate and install the correct drivers.
terMinaL port
As an alternative, the PC can be connected to the Terminal Port. The Terminal Port cable should be kept
to a minimum distance, preferably less than 20'. MICRO‑AIDE provides, as a standard feature, an RS‑232
DE‑9 to DE‑9 cable. The cable is suitable for use with any PC comm port or USB‑to‑serial adapter cable.
Each logger is shipped with a pair of MICRO‑AIDE manufactured RS‑232 cables. Both cables are wired
identically and can be used interchangeably with the Terminal and Vital‑Processor Ports. The shield wire
in each cable is not attached. Consequently, the logger chassis and peripheral device are electrically
isolated. This further improves the isolation properties of the system.
VitaL‑proCeSSor port
The VDL logs Event Records for Digital Inputs by establishing a communications connection with the
Siemens S7‑300. Accordingly, the VDL port labeled “To Vital‑Processor” must be connected to the CP 340
Communications Port.
ethernet port (optionaL)
The optional Ethernet Port may be used to connect the VDL to a LAN or PC. A standard CAT‑5 Ethernet
cable is used to connect to the LAN via a hub or switch. The length of either cable must be limited to 50'.
Table 14 on page 87 lists the bit transfer rates of each user‑accessible port.
internaL MoDeM (optionaL)
If the VDL is equipped with the optional internal modem, a standard telephone line can be attached to
the logger. The telephone line must be terminated with an RJ‑11 connector like those commonly used in
residential telephone service. Test the telephone line rst to ensure that a dial tone is available.
gpS reCeiVer (optionaL)
The GPS Receiver option is the preferred means of precisely controlling the logger’s real‑time clock. The
optional feature includes a bulkhead‑mount antenna designed specically for use with the receiver
module. For improved reception the antenna should be mounted outside of the equipment house or
cabinet, as it requires unobstructed skyward access. The antenna is designed to be moisture proof and is
rated to operate over a broad temperature range.
The antenna is equipped with a 16' coaxial cable. The antenna end of the cable is non‑detachable. The
other end of the cable terminates in an MCX‑male connector. The MCX connector must be secured to
the logger’s connector labeled “GPS Antenna” located along the top panel.
