Protocol Parameters

The citect.ini file contains the following protocol parameters:

[<ProtocolName>]Block - The blocking constant is a trade-off between the time taken to make multiple data requests and the time taken to read more data in a single request.
[<ProtocolName>]Delay - The period (in milliseconds) to wait between receiving a response and sending the next command.
[<ProtocolName>]MaxPending - The maximum number of pending commands that the driver holds ready for immediate execution.
[<ProtocolName>]PollTime - The interrupt or polling service time (in milliseconds). Setting the polling time to 0 puts the driver in interrupt mode.
[<ProtocolName>]Retry - The number of times to retry a command after a timeout.
[<ProtocolName>]Timeout - Specifies how many milliseconds to wait for a response before displaying an error message.
[<ProtocolName>]WatchTime - The frequency (in seconds) that the driver uses to check the communications link to the I/O device.
Note: The default and allowable values of these parameters are specific to the protocol. To set the parameters for your protocol, select your manufacturer and protocol from Help topics finder, and then select the Protocol Parameters topic for that protocol.
