can be changed on a device-by-device basis by altering the TimeDownLoad Period
parameter for an individual device in the .ini file. The value should be entered in
milliseconds. Note that increasing this value will free up processor time for the
Server’s use, but may allow devices to slip out of sync with the Server’s clock.
Decreasing this value causes the Server to spend more of its time synchronizing
device clocks and leaves less time available to process client requests for data.
NOTE: A related value, the Time Download Start Addr, is used by the Server to
address time-synchronization messages to devices. DO NOT CHANGE THIS
VALUE. If this value is changed, the device will not be able to time sync with the
DDE Server.
ExitDisable
This setting allows users to close the DDE Server. It's default setting is Disable when
PMCS DDE Server is installed as NT Service, and Enable when PMCS DDE Server
is installed as a standard application.
UIHide
This setting controls whether or not the DDE Server's user interface is visible to the
user. It's default setting is Unhide (program visible to user).
Bear in mind that if you change parameters of the .ini file, such as increasing the
Communication Time-out Factor, the Maximum Query Retries or the Dead
Device Scan Interval, you will slow down your network performance. On the other
hand, if you reduce these values, you may generate unnecessary time-outs or have
devices declared dead when they are not actually off-line.
Please avoid changing any other parameters of the .ini file beyond those listed here,
as doing so may adversely affect Server performance.
