    3.1 Precautions Concerning Installation Noise resistance The Ethernet is a network used in offices and buildings, where there is comparatively little noise. It does not have a higher resistance to noise than ordinary FA application networks. Consequently, caution is required when installing the transceiver and hub, and when laying cables. Guidelines to noise generation If any of the following are occurring, there is a danger that external noise is affecting the communication circuit.
  • Page 31 If it is impossible to avoid installing the equipment or cables near noise-generating equipment, the following measures should be taken. Place the programmable controller, transceiver, and hub inside metal panels. Place communication cables inside metal ducts. Attach a ferrite core near the ET-LAN unit of the communication cable. If using an external power supply terminal (12 V DC) for the ET-LAN unit, attach a ferrite core to the power supply cable.

After checking the e-mail status area: If the status is found to be as noted below, check the e-mail settings and re-set them if necessary. The e-mail send conditions set for the ET-LAN unit are met, but the number of e-mail send complete times and the number of e-mail send error are not counted.

The ET-LAN unit is equipped with a log buffer where hardware and communication errors that occur in the unit are recorded. The contents of the log buffer are read by using the shared memory access instructions F150 (READ) and P150 (PREAD) and F151 (WRT) and P151 (PWRT) to read from and write to the error log area of the shared memory.
