RS232 data log output
In addition to Modbus, an additional data stream showing actions within the FMC-60
system is available via the RS232 output.
This consists of a 3 wire interface which can connect directly into the serial port (RS232)
connection on a PC which is a 9 way D-type female connector (not supplied). This should
be wired to the FMC-60 system as follows.

Using HyperTerminal on the PC and set up at 2400 baud 8 bit no parity and no
handshake, the data output should appear on the screen and consists of the following.
1)Time and date is sent every hour
2)Sensor gas values are sent if any of the gasses on any sample line have changed,
together with the date and time of the change.
Event log
(9)
The events listed in appendix 1 are logged internally in the FMC-60 system.
A total of 99 events can be stored and viewed later either on the LCD or on a PC using
Hyper Terminal.
When this 99 event memory is full, the oldest event is replaced by the new event so this
history of events always represents the last 99 incidents.
Using ENGINEERS menu number 9, this event memory can be viewed one event at a
time using the UP and DOWN buttons to scroll through the sequence. Date and time of
the event is also displayed.
With the RS232 cable connected to the PC and Hyper Terminal in use at 2400 baud the
whole event log can be sent using ENGINEERING menu 28.
using capture text in Hyper Terminal, this event log can be saved to a file for future
examination or printing etc.
