Up/Down Counter 100 kHz, 750-404
Technical Description:
Attention! The description that is in the I/O ring binder data pages (88-530/013-600 dated 7/96) is not correct. The bottom contacts are additional outputs.
Attention:
The lowest power jumper contact is not carried out for some modules (e.g. 4-channel)! A module which needs all contacts (e.g. 2 channel digital) may not be connected to the right hand side of modules which do not have 3 power jumper contacts (e.g. 4 channel modules).
The described configuration is counter with up/down input.
The following description is preliminary and is applicable to the factory configuration.
The counter module is able to run with all WAGOÇI/OÇSYSTEM bus-couplers (except for the economy type).

Organization of the inand output data:
The counter begins processing with pulses at the CLOCK input. The changes from 0 V to 24 V are counted.
The counter counts up, if the input U/D is set at 24 V. With an open circuit input or 0 V the counter counts backwards.
The two bottom contacts each include another output. These outputs are activated through bits in the control byte.
The control byte has the following bits:
Control Byte
Bit 7 |
Bit 6 |
Bit 5 |
Bit 4 |
Bit 3 |
Bit 2 |
Bit 1 |
Bit 0 |

With the control and status-byte the following tasks are possible:
Set the counter: Put Bit 5 into the control byte. The counter with the 32 bit value is loaded into output bytes 0-3. As long as the bits are set, the counter can stop and information is stored. The ensuing data of the counter will be conveyed to the status byte.
Blocking the counter: Bit 4 is set into the control byte, then the count process is suppressed. Bit 4 in the status byte communicates the suppression of the counter.
Set the outputs: Bits 2 and 3 set the additional two outputs of the counter module.
The result of the counter is in binary.

An example:
The counter is set with “Set Counter” to the value 0x0000.0000
- 0X1X.XXXX, 0x00, 0x00, 0x00, 0x00 are carried over as output value (carry over the control-byte and the new counter position),
-wait until the input value is 0X1X.XXXX, 0x00, 0x00, 0x00, 0x00 (the status-byte shows the loading feedback) ,
-carry over 0x00, 0x00, 0x00, 0x00, 0x00 as output value (release counter).
Wait for the first and further counting pulse |
|
-the input value is XX00.XXXX, 0x00, 0x00, 0x00, 0x00 |
(no counting pulse received) |
-the input value is XX00.XXXX, 0x00, 0x00, 0x00, 0x01 |
(1 counting pulse received) |
-the input value is XX00.XXXX, 0x00, 0x00, 0x00, 0x02 |
(2 counting pulses received) |
-.................
-the input value is XX00.XXXX, 0xFF, 0xFF, 0xFF, 0xFF (maximum counting position is reached)
-the input value is XX00.XXXX, 0x00, 0x00, 0x00, 0x00 (a further counting pulse causes an overflow)
-the input value is XX00.XXXX, 0x00, 0x00, 0x00 0x01, (a further counting pulse is received)
Notes: 0x23 is a value in hexadecimal form 0101.1001 is a value in binary form
“X” is used if the value at this position is without any significance.

Counter with enable input 750-404/000-001
Technical description:
The counter module also can be ordered as counter with enable input (750-404/000- 001).
The counter begins processing with pulses at the CLOCK input. The changes from 0 V to 24 V are counted.
The counter counts down if the input U/D is set at 24 V. With an open circuit input or 0 V the counter counts up.
The data format of the module is 4 bytes data and a control/status byte. The module is a 32 Bit counter. The ID Code os 180 (0xB4). The format of input and output data is the same as 750-404.
The counter module is able to run with all WAGOÇI/OÇSYSTEM bus-couplers (except for the economy type).
