The time required for the controller to execute the instructions in the program. The programme scan time may vary depending on the instructions and each instruction’s status during the scan.
Industry:Automation
1) To transfer a block (64 words maximum) of data to or from an I/O module in one scan. 2) Contrasted with single-transfer
Industry:Automation
A set of records stored in one order and linked in a different logical order by insertion of pointers in each record. In a list, the logical order or sequence of records is different from the physical order.
Industry:Automation
Root Mean Square. The effective value of an alternating current, corresponding to the dc value that produces the same heating effect. The rms value is computed as the square root of the average of the squares of the instantaneous amplitude for one complete cycle. For a sine wave, the rms value is 0.707 times the peak value.
Industry:Automation
1) A mode of operation for a point-to-point link with two physical circuits, in which messages or transmission blocks can be sent in both directions at the same time. 2) Contrasted with two-way alternate.

Industry:Automation
1) To transfer a single unit (8, 16, or 32 bits) of I/O data to/from each I/O module in an I/O chassis. The size of the unit of I/O data depends on the density of I/O addressing in the I/O chassis 2) Contrasted with block transfer
