  • Page 13 The above restrictions do not apply to Multi−wire Link Units set to the MEWNET−F mode and MEWNET−W2 mode. Note If the FP2 CPU unit is being used, make sure the restrictions relating to the following communication conditions have been carefully confirmed when deciding the number of units to be installed.
  • Page 14 Relating to Functions 1.4.1 Precautions when Using the FP2 CPU Unit −1 If the processing of commands and responses sent from a host computer or display panel extends over multiple frames, a busy error (error code 53) will be returned to other ports if communication is currently being carried out on one port, and communication will be inhibited on those other ports.
  • Page 15 − If using the FP2SH CPU unit, the above restriction does not apply. 1.4.2 Precautions when Using the FP2 CPU Unit−2 Of the commands sent from a host computer or display panel, if the monitor commands (the MC, MD, and MG codes) are used, they cannot be read accurately if two or more devices within the same group are connected.
