Chapter 1 Introduction
1.1 General
The Micro-Tech 3104 is a bus-based microprocessor instrument equipped with one
COMM A (on Mother Board) that can be equipped (optionally) with a second serial
communication boards. Each COMM A board has one serial channel that can be
configured according to the following standards.
!RS423/RS232C For point to point asynchronous bidirectional
communications, maximum 50 feet (15 m). Modem
capability.
!RS485/RS422 For point to point or multidrop 4 wire bidirectional
communications, maximum 4000 feet (1200 m).
!Current Loop For high immunity bidirectional asynchronous
communications. Passive only.
All of the above are optically isolated.
COMM A board (Optionally) can be installed in any available mother board expansion
slot. After installing the board and power has been restored, the instrument
automatically detects the new board and adds the communication set-up scrolls to
the Main Menu scrolls. The Micro-Tech refers to the COMM A on the Mother Board
as COM 1, and the COMM A board (if installed) as COM 2.
If two COMM A are availables; one can be set up for printing, the other one for
transferring data to and from other intelligent devices such as computers and PLC's.
The system cannot support two printers or two COMM lines.
Each COMM A contains a perpetual clock/calendar circuit with battery backup. The
battery is located on the mother board and is the same battery used for system
memory backup. The system automatically detects and uses the clock calendar
circuit of the first board and ignores the second.
Time and date set-up screens become visible after the COMM board is installed.
The Micro-Tech 3000 Integrator COMM meets the year 2000 requirements.
1.2 Communication Protocols
When a COMM line is set up for communication (not for a printer), the system is able
to send and receive data to and from another device connected to the COMM line.
The COMM option comes with the following software communication protocols
already built in:
- PC-Master A Thermo Ramsey proprietary protocol, multidrop.
- Modbus An AEG proprietary protocol, multidrop. The COMM option only
contains a subset of the protocol as specified in this manual.
- Allen-Bradley A proprietary protocol, multidrop. The COMM option only contains
a subset of the protocol in the PLC-5 version of it, as specified in
this manual.
- 3964R A Siemens proprietary protocol, single point.

Serial Communications 3104
REC XXXXX1-2
The hardware can be configured (through jumpers on the Mother Board and on the
optinally COMM board if available) to one of the three standards as listed in the
previous paragraph. However, only the RS485/RS422 standard allows multidrop
communications, RS232C and Current Loop can only be used in point to point mode.
This does not prevent the use of a protocol; it only prevents physically connecting the
Micro-Tech 3000 to more than one device.
CAUTION
The communication protocols have been implemented and tested as
described in this document or in other referenced documents. It is
the intention of Thermo Ramsey to provide all the necessary
information and help the user to connect the instrument to other
compatible devices. However, because most of the protocols are
specific to other manufacturers, Thermo Ramsey declines any
responsibility for any malfunction that may occur when connecting
the instrument to devices of other manufacturers, unless tested and
approved by Thermo Ramsey.
1.2.1 Protocol Rules
The communication protocol allows a remote intelligent device to read and
eventually write information from and to the Micro-Tech 3104. For
convenience, the information is organized in a set of registers as listed in this
document.
During the communication activity, the Micro-Tech 3104 always acts as Slave,
meaning it responds to a request from a Master device on the line, but never
attempts to send messages out.
The following rules apply:
a. The Micro-Tech 3104 responds only if the message is completely
received.
b. The Micro-Tech 3104 reads the message and looks for the address,
which is contained into an address byte in the query package. The
message is then processed only if the address matches the one specified
in the set-up data of the Micro-Tech 3104, otherwise it is ignored.
c. When the system receives a message, the integrity of the message is
checked. An answer-back message is prepared if the message is
formally correct.
d. When a message containing a variable to be written in memory is
received, the system checks the correctness of the message and, if it is
correct, immediately sends the answer-back message. This does not
always mean the data is written in memory. The system first checks the
register number (which must correspond to a valid address of a variable),
then the minimum and maximum limits, and then the password. If data
can be accepted, it is stored in memory and the success flag is set to 0
(no error). If not, it is set to 1. To know if the last variables sent have
been stored, the Master checks (reads) the success flag contained in a
read only register.
The following procedure applies:
- The Host sends data to the Micro-Tech 3104.

Serial Communications 3104
REC XXXXX 1-3
- The Host waits at least 100 ms.
- The Host reads the success flag. It should be 0.
Some data is read only, some is read write, and some is write only.
WARNING
In all cases, the maximum number of words the system can transfer
is limited to 41 per time. Requests of registers in excess of 41 are
considered errors and do not generate an answer.
1.3 Printer
When a COMM line is set up for printing, the system prints out data in different ways,
depending on the set-up. Print menus become visible that allow the user to define
when and in which format the data is printed.
1. Periodical printouts at predefined intervals, as well as at predefined times of
day, or on command is possible.
2. The format of the printouts is selectable between a number of predefined
formats, plus a fully programmable user defined format. In this particular case,
the user is able to easily format the printout to fit into any pre-printed ticket or
form, without the need of special software.
1.4 Thermo Electron Warranty
The seller agrees, represents, and warrants that the equipment delivered
hereunder shall be free from defects in material and workmanship. Such
warranty shall not apply to accessories, parts, or material purchased by the

Installation
2.1 General
This chapter describes the installation procedure and hardware configuration for the
communications (on Mother Board and on Comm A Board option). If the
communication option was installed at the factory, it may not be necessary to
continue with this chapter. Proceed to Chapter 3.0, Operation.
2.2 Comm A Board (Option) Installation
To install the COMM A board, proceed as follows:
1. Select the jumper positions on the COMM A board for the desired
communication standard. Below is a table which summarizes the jumper
positions for selection of the electrical interface. Refer to Figure 2-1 for jumper
locations.

2. Open the Micro-Tech wall mount enclosure and turn power off at the mains,
or remove panel mount enclosure from the panel and remove top cover
allowing access to the mother board.
3. Remove the field mating connector. Wire the connector per the supplied
field wiring diagram or install field terminal board cable (wall mount only).
4. Remove the hex head mounting screw from the connector end of the COMM
board.
5. Insert the COMM board in any available expansion slot on the mother board
(see Figure 2-2).

6. Insert the hex head screw through the chassis and tighten.
7. Install the wired mating connector on the COMM board connector.
8. Reinstall panel mount enclosure in the panel.
9. Turn power back on. The following screen appears when power is applied
and remains on for 10 seconds.
The screen disappears after 10 seconds if the question is not answered, and
the Micro-Tech 3104 assumes the answer is NO. "HW CONFIG. CHANGED"
alarm is on and cannot be reset. The above screen appears each time power
is cycled if the question is not answered.
Answer YES because this is a hardware configuration change.
10. This completes the installation procedure.
11. Set-up data for the newly installed COMM board must now be
entered. Proceed to Chapter 3.0, Operation.
