    JetWeb Appendix B: Overview of Registers For communication with the CPU, 10 registers are provided by the JX2-IO16 module. In addition, a register array is available, which can be addressed via register 8, and register 9. When doing so, register 8 indicates the index of the register array element, and register 9 contains the value of the element.

    The Jetter system bus is a system-bus system with a cable length of max. 200 m, and a data transmission rate of 1 Mbit/s. In addition to this, the Jetter system bus is highly immune to interferences. Therefore, the Jetter system bus is suited to realise field bus applications in a limited space.
