Data can be read and written from/to the sequencer from external devices (PC, display, etc.) using the MC protocol. Non-procedural protocol communication is supported to permit data exchange between the sequencer and a given external device (barcode reader, measuring instrument, etc.) in any communication protocol specified by the external device. Sequencers can be programmed and monitored from a programming tool based on RS-232 serial communication using the QJ71C24N(-R2). The QJ71C24N(-R2) has a function supporting public network modems and is capable of initializing an applicable modem and connecting with the other device to communicate with any remote device or programming tool via the modem and a public network. The QJ71C24N(-R2) has a remote password function that prevents illegal access to the Q-series sequencers using the QJ71C24N(-R2)'s modem function.
