  • Page 34: Addressing And Programming

    IP 267 Addressing and Programming Addressing and Programming The IP 267 can be plugged into slots 0 to 7 of the S5-100U programmable controller. There are eight bytes reserved for each slot in both the process input image (PII) and the process output image (PIQ) and data exchange is via the first four bytes of the PII and the PIQ.
  • Page 35 Addressing and Programming IP 267 The IP 267 exchanges data with the CPU of the programmable controller via the serial interface. The user writes configuration data and positioning jobs into the process output image (PIQ). From there this data is transferred once in every data cycle to the IP 267.

  • Page 36: Configuring The Ip 267

    IP 267 Addressing and Programming Configuring the IP 267 The IP 267 must always be configured after commissioning or after deleting valid configuration data. The data is transferred to the IP 267 only after applying the emergency limit switches (PDs). The first data set transferred from the PC to the IP is interpreted as the configuration message frame, provided the multiplier for the start/stop rate is not zero and the configuration bits are reset (KB0=0 and KB1=0).

  • Page 40: Deleting The Configuration

    IP 267 Addressing and Programming The values for frequency and acceleration/deceleration in Table 4-4. only apply if you set reduction factor 1 in the positioning job (bit R="0"). Divide the values given by 10 (bit R="1") for reduction factor 0.1. The pulse duration is not affected by this.

    Notes on Operation IP 267 Determining a Reference Point Reference points calibrate the drive system and determine a system zero point for the following positioning jobs. To calculate the reference point, you can install a separate switch (position switch, BERO, etc.) within the traversing range that will send a signal to the REF reference input when triggered.

  • Page 67: Determining A Reference Point With Limit Switches

    IP 267 Notes on Operation Then you assign a "Start forwards" job setting a start/stop rate. Pulse output immediately stops when the reference switch is detected. The position reached is the reference point for further positioning jobs. Start forwards Starting point Start backwards Figure 5-4.

    Notes on Operation IP 267 You then continue to the limit switch with "Start forwards" and at the start/stop rate. The traversing movement stops immediately when the limit switch is reached. You can re-establish this reference point at any time with step accuracy if you approach it with the same pulse frequency from the same direction.

    Application Examples IP 267 Determining Reference Points with Separate Switch A reference point is always determined in three approach sections (search for reference point switch, overtravel reference point switch and approach reference point switch slowly). Additional auxiliary approach jobs are required, for example, if the reference switch is blocked by the drive.
