FP2−CCU | Functions of Computer Communication Unit |
1.4 Communication Conditions and Restrictions Relating to Functions
Tip
−“Multiple frames” means that, if a command or response exceeds 118 bytes, the command or response is divided into multiple segments and transmitted or received.
For example, this applies in cases such as when a program is read from a tool port, when commands, which continuously read multiple data, are transmitted from a host side.
−If using the FP2SH CPU unit, the above restriction does not apply.
1.4.2Precautions 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.
