Communication with the PLC
6.4.10 Example: Remote control with parameter adjustment for the E20
H is the handshake bit and switched by the master and with each data transmission via the
parameter channel (see section of "6.4.1 Layout of the parameters channel - data access control")
1. Terminate current activities via I/O or process channel
2. Open parameter channel with service "Open parameter channel"
- Transfer:
- Wait for answer:
- In case of a collision: Undo the collision with the service "Empty service", remove the cause of the collision and
open again. If necessary evaluate fault number in application data bytes.
3. Set sensor number to the desired program index (e.g. program number 7, sensor number 1)
- Transfer:
- Wait for answer:
- In case of a collision: Undo the collision with the service "Empty service", remove the cause of the collision and
open again. If necessary evaluate fault number in application data byte
4. Set nominal thickness to the desired program index (e.g. program number 7, 1.00 mm)
- Transfer:
- Wait for answer:
- In case of a collision: Undo the collision with the service "Empty service", remove the cause of the collision and
open again. If necessary evaluate fault number in application data byte
5. Set the lower limit to the desired program index (e.g. program number 7, 80%)
- Transfer:
- Wait for answer:
- In case of a collision: Undo the collision with the service "Empty service", remove the cause of the collision and
open again. If necessary evaluate fault number in application data byte
6. Set the upper limit to the desired program index (e.g. program number 7, 120%)
- Transfer:
- Wait for answer:
- In case of a collision: Undo the collision with the service "Empty service", remove the cause of the collision and
open again. If necessary evaluate fault number in application data byte
7. Close Parameter channel
- Transfer:
- Wait for answer:
- In case of collision: Undo the collision with service "Empty service", remove the cause of the collision
(normally only wrong content or checksum are possible) and close. If necessary evaluate fault number in application
data bytes.
8. Switch program number via the process channel (e.g. switch to program number 7)
- Transfers:
- Answer:
- Transfer:
- Answer:
- In case of malfunctioning the "Function fault" is returned (see also section "6.3 Process channel")
9. Execute zero adjust via the process channel (without sheet in front of the sensor)
- Transfer:
- Answer:
- Transfer:
- Answer:
- In case of malfunctioning the "Function fault" is returned (see also section "6.3 Process channel")
10. Execute teach-in via the process channel (attach sheet with nominal thickness to the sensor)
- Transfer:
- Answer:
- The thickness from the curve is sent to byte 10 and 11. If the issued thickness deviates more than 10%
(exceptions 20%) of the nominal thickness, then it is necessary to search for the cause. This could be:
wrong sheet, wrong thickness, warped sheets, air gap between sensor and sheet.
- In case of malfunctioning the "Function fault" is returned (see also section "6.3 Process channel")
11. Open, if necessary, the parameters channel again and read the internal program parameter (1-13) of the
selected programs and store the data backup in the PLC. Then close the parameters channel again.
