Brand advantage: Allen Bradley, BentlyNevada, ABB, Emerson Ovation, Honeywell DCS, Rockwell ICS Triplex, FOXBORO, Schneider PLC, GE Fanuc, Motorola, HIMA, TRICONEX, Prosoft etc. Various kinds of imported industrial parts
Products are widely used in metallurgy, petroleum, glass, aluminum manufacturing, petrochemical industry, coal mine, papermaking, printing, textile printing and dyeing, machinery, electronics, automobile manufacturing, tobacco, plastics machinery, electric power, water conservancy, water treatment/environmental protection, municipal engineering, boiler heating, energy, power transmission and distribution and so on.
Devices may only be connected to or disconnected from the networking interface with all supply voltages switched off. In order to assemble the two devices with each other, they must be put together on a level ground and then be fastened using the connecting element.
The high-speed counter used in the central units 07 KR 91, 07 KT 92 and 07 KT 93 works independently of the user program and is therefore able to response quickly to external signals. Its features are as follows: The counting frequency is max. 50 kHz. The counter counts the 0–>1 edges at terminal 02 (also designated as E 62,00). The counter counts upwards from –32768 to +32767 (8000H...7FFFH). If +32767 is exceeded, the counter skips to –32768. Sequence of the counting procedure:Enabling/disabling of the counting procedure using the internal variable A 63,14 in the user program: – A 63,14 = 0: The internal variable A 63,13 = 1 enables the counting procedure, whereas A 63,13 = 0 disables it. – A 63,14 = 1: Signal 1 at terminal 03 (also designated as E 62,01) enables the counting procedure, whereas signal 0 disables it. A 63,13 is without effect. Note: The dead time may be 0...1.5 ms.
– to the value contained in the internal word variable AW 06,15 – using the internal variable A 63,15 = 1. Note: If the internal variable A 63,15 = 1 is present during several processing cycles, the processor sets the counter at the program end in each case. During the remaining time of the processing cycle, the counter counts pulses at terminal 02. The counter content can be read via the internal variable EW 06,15. Zero-crossing message (signal changes from 0 to 1 when the counter contents changes from –1 to 0): – always via the internal variable E 63,13, – at the terminal 41 (also designated as A 62,00) only, if the internal variable A 63,14 = 1 is set. Note: The reaction time may be 0...1.5 ms. The direct control of the output A 62,00 from the user program is disabled by A 63,14 = 1. The zero-crossing message is cancelled when the counter is set.
Task: – 180 pieces each of a unit load have to be filled into a packing. – Each filled-in piece generates one pulse. – When the packing is full, the counter is immediately prepared for the next filling operation. – The enabling signal for the filling operation is sent by the packaging machine. – The end of the counting operation has to be signalled to the packaging machine immediately. Wiring – Connect the signal line for the counting pulses to terminal 02. – Connect the signal line for the enabling of the counting operation to terminal 03. – Connect the signal line for ”zero crossing” of the counter to terminal 41.
