In 1979, Honeywell Information Systems announced a new programming language for their time-sharing service named TEX, an acronym for the Text Executive text processing system. TEX was a first-generation scripting language developed around the time of AWK and used by Honeywell initially as an in-house system test automation tool.
A Honeywell 316 at the Computer History Museum Honeywell 316 control panel. The Honeywell 316 was a popular 16-bit minicomputer built by Honeywell starting in 1969. It is part of the Series 16, which includes the Models 116 (1965, discrete [1]: 4 ), 316 (1969), [2] 416 (1966), 516 (1966) [3] [4] and DDP-716 (1969). [5]
Many vendors whilst incorporating the full IEC 61131-3 requirements have additional vendor specific calls/function blocks to suit their hardware such as reading or writing to I/O. Siemens PLC instruction list language is known as "Statement List" or "STL" in English, and "Anweisungs-Liste" or "AWL" in German, Italian and Spanish.
Like the earlier Microdata port, this was a firmware implementation, with the Pick instruction set in firmware and the monitor in assembly code on a Honeywell Level 6 machine. The system had dual personalities in that the monitor/kernel functions (mostly hardware I/O and scheduling) were executed by the native Honeywell Level 6 instruction set.
In the real world some low-end devices may only support a subset of these 488.2 commands, or may even accept the commands but not perform any operation. A user should check the official programmers manual for each device before assuming all of these 488.2 commands are supported.
Programming the morning temperature to be 21° C at 7:00 a.m., for instance, ensures that the temperature would then be 21 °C, whereas less sophisticated programmable thermostat would simply start working toward 21° at 7:00 a.m. Thus a PID controller sets the time at which the system should be activated in order to reach the desired ...
Programming the EDSAC was in the first generation of programming language. The first generation of programming language is machine language. [45] Machine language requires the programmer to enter instructions using instruction numbers called machine code. For example, the ADD operation on the PDP-11 has instruction number 24576. [46]
After a program was loaded, the value of individual memory locations can be altered using the console buttons. The Honeywell 200 was a character-oriented [ 1 ] : 70C-4S0-01n two-address commercial computer introduced by Honeywell in December 1963, [ 2 ] the basis of later models in Honeywell 200 Series, including 1200, 1250, 2200, 3200, 4200 ...
