Compressing the I/O Compressing re-allocates all I/O modules in an area as close to the start of Mapping the area as possible. Compressing an area does not change the sequence of the slave devices and/or the I/O modules.

To ensure that I/O data transferred through the interface can be used on both sides of the interface without additional formatting, the CS1/CJ1W-PRM21 PROFIBUS Master Units perform the necessary data formatting.

    User initiated Global-Control commands can be transmitted to either all slave devices allocated to a Master Unit, or to one or more of up to eight groups of slave devices. The group addresses are defined by up to eight bits in a group address byte, which is part of the Global-Control command.

To define the group assignment of a slave device, through the Generic Slave DTM, refer to section 3-3-3 Selecting the Group Assignment.
