11. T-LOG polling

All REG-mode transaction data in each satellite is saved in its T-LOG buffer. T-LOG polling is a data collecting system in which the master collects data from the T-LOG buffers in satellites.

A request for T-LOG polling is issued from the satellite to the master when the number of data records in its T-LOG buffer exceeds a predetermined number.

As the master detects such a request, it starts collecting T-LOG buffer data. After collecting data from one satellite, the master waits for a preset time and starts collecting data from another satellite. In T-LOG polling, the data transmitted to the master is stored in the corresponding file.

The data flow in T-LOG polling is shown below.

Polling sequence (see the figure above.)

(1)Satellite A makes a request for polling.

(2)The master detects the request and starts collecting T-LOG data from satellite A.

(3)The T-LOG data is sent to the master.

(4)After receiving T-LOG data from satellite A, the master waits for a preset time.

(5)The master detects a request from another satellite (B, C or D) and starts polling for it.

You can specify in the PGM2 mode whether the entry function of a satellite is disabled (LOCK) or enabled (CONTINUE) when the T-LOG buffer is full.

If it is disabled, an error message “T-LOG FULL” will be displayed and you are not allowed to make any entry in the REG/MGR mode at the satellite.

If it is enabled, you can continue entries but cannot save the entered data. Even if data is entered after the T-LOG buffer becomes full, the previous data saved in the file will not be erased.

	NOTE	• If the T-LOG buffer becomes nearly full, an alarm message pattern appears on the display of
	NOTE	the satellite.
		the satellite.

•For the programming whether or not to lock a registration entry when the T-LOG file is full, see the “Function selection 2” of “Optional Feature Selection” section of the UP-820F/UP-820N Instruction Manual.

•For the T-LOG polling between the master and MWS, please consult your authorized SHARP dealer.
