Basic module and Expansion module are connected by using 34-pin flat cable.
Install Basic module left side of Expansion module in order to prevent the I/O Link connector from being covered with the flat cable.

I/O module type-2 is allocated a group of DI addresses(16 bytes) and a group of DO addresses(8 bytes). Expansion module can be added or removed as required.
The reason for this address allocation is explained below. The MPG interface (MPG counter) occupies a DI space from Xm + 12 through Xm + 14. These address are fixed regardless of whether Expansion module is used, and Xm + 12 through Xm + 14 must be allocated as a DI work area to enable the use of the MPG. Therefore, when using a MPG, allocate DI addresses in units of 16 bytes. Do not use the DI space from Xm + 12 through Xm + 14 for Ladder; the CNC process the MPG counter value directly.
DI address Xm+15 is used for detecting over current and overheating alarms that occur in the IC used in the DO driver. This address is fixed regardless of whether Expansion module is used, and it must be allocated as a work area before it can be used.
When using this area, therefore allocate DI addresses in unit of 16byte.

The DO driver of the Basic module and Expansion module is capable of detecting an over current and measuring its own temperature. If an accident, such as the connecting of the cable to ground, causes an abnormal increase in the load current or in the driver temperature, a protection circuit , which is provided for each DO driver(1 byte), is activated and keeps the DO signal for the relevant 1 byte in the OFF state until the cause of the problem is eliminated. Even if this occurs, the CNC and I/O module continue operating. The DI address(Xm + 15) identifies the DO driver which has detected the alarm. The following table shows the correspondence between the DI address(Xm + 15) bits and the DO addresses. Manage the alarm well by using Ladder program with bit signals in following table, when DO status becomes abnormal.
