2. HOST COMMUNICATION
IMR02F04-E1
12
Interval time:
The interval time for the PG500 should be set to provide a time for host computer to finish
sending all data including stop bit and to switch the line to receive status for the host. If the
interval time between the two is too short, the PG500 may send data before the host computer is
ready to receive it. In this case, communication transmission cannot be conducted correctly.
2.3.3 Setting Procedure Example
This example shows how to set the following values.
Communication protocol: RKC communication
Device address:
0
Communication speed:
38400 bps
Data bit configuration:
Data 8-bit, Parity bit without, Stop 1-bit
Interval time:
50 ms
When all communication parameter settings have been completed, turn the power off and
then on to make the new set values take effect.
If you have locked the PG500 setting data so that it cannot be changed, the lock must be released
before configuring the communication settings.
To release the lock, refer to
Set lock level
(
LCK
)
of
PG500 Operation Manual
(IMR02F02-E
)
.
Press the
key to store the new value. If the
key is not pressed within one minute, the
display returns to the measured value (PV) monitor screen and the set value returns the previous
setting.
For details on changing the numeric value, refer to
PG500 Operation Manual (IMR02F02-E
)
.
Parameters in the Engineering mode (F10 to F91) should be set according to the
application before setting any parameter related to operation.
Once the parameters in the Engineering mode are set correctly, no further
changes need to be made to parameters for the same application under normal
conditions.
If they are changed unnecessarily, it may result in malfunction or failure of the
instrument.
RKC will not bear any responsibility for malfunction or failure as a result of
improper changes in the Engineering mode.
