Overview

Essential details：A1S68DAV A series digital/analog conversion module Mitsubishi

Install a safety circuit external to the PC that keeps the entire system safe even when there are problems with the external power supply or the PC module. Otherwise, trouble could result from erroneous output or erroneous operation.

(1) Outside the PC, construct mechanical damage preventing interlock circuits such as emergency stop, protective circuits, positioning upper and lower limits switches and interlocking forward /reverse operations.

(2) When the PC detects the following problems, it will stop calculation and turn off all output.

  • The power supply module has over current protection equipment and over voltage protection equipment.
  • The PC CPUs self diagnostic functions, such as the watchdog timer error, detect problems. In addition, all output will be turned on when there are problems that the PC CPU cannot detect, such as in the I/O controller. Build a fail safe circuit exterior to the PC that will make sure the equipment operates safely at such times. Refer to Section 5.1 of this user’s manual for example fail safe circuits.

(3) Output could be left on or off when there is trouble in the output module relay or transistor. So build an external monitoring circuit that will monitor any single output that could cause serious trouble.

  • When overcurrent which exceeds the rating or caused by short-circuited load flows in the output module for a long time, it may cause smoke or fire. To prevent this, configure an external safety circuit, such as fuse.
  • Build a circuit that turns on the external power supply when the PC main module power is turned
  1. If the external power supply is turned on first, it could result in erroneous output or erroneous operation.
  • When there are communication problems with the data link, the communication problem station will enter the following condition.

Build an interlock circuit into the PC program that will make sure the system operates safely by using the communication state information. Not doing so could result in erroneous output or erroneous operation.

(1) For the data link data, the data prior to the communication error will be held.

(2) The MELSECNET (II,/B,/10) remote I/O station will turn all output off.

(3) The MELSECNET/MINI-S3 remote I/O station will hold the output or turn all output off depending on the E.C. remote setting.

Refer to the data link manuals regarding the method for setting the communication problem station and the operation state when there are communication problem.
