5 Modules
5.6.3 215IF Communications Module (215IF)
5-126
„ Rotary Switches
The SW1 and SW2 are used to set the station address on the 215IF transmission. The SW1
sets the 1s digit (
×1) and the SW2 sets the 10s digit (×10). Set a station address between 1
and 64. The SW1 and SW2 are valid only when the INIT of SW3 is set to ON.
„ DIP Switch (SW3)
The SW3 is used to set the operation mode such as transmission speed and self-diagnosis.
All the pins of SW3 are set by default to OFF (to the right).
„ INIT Pin of DIP Switch SW3
When the power is turned ON with the INIT pin set to ON, the 215IF Module executes message com-
munications according to the station addresses set by SW1 and SW2, the transmission speed set by
BRS0 and BRS1 of SW3, and the network address set by SW4. In this case, the link communication is
not executed and the relay function is disabled.
When the power is turned ON with the INIT pin set to OFF, the 215IF Module executes the link com-
munications and message communications according to the settings in the Module Condiguration Def-
inition Window of the MPE720. In this case, the settings of SW1, SW2, BRS0 and BRS1 of SW3, and
SW4 will be ignored.
To perform engineerings such as programming and register display on the MPE720 using the 215IF
Module when no module configuration definition is set, set the INIT pin to ON. Set the INIT pin to
ON only when forcibly communicating with the MPE720 such as when the CPU memory is cleared.
Indicator Name Setting Function
ADRS × 1 ADDRESS × 1 0 to 6 Sets the station address 1s
digit.
ADRS × 10 ADDRESS × 10 0 to 6 Sets the station address 10s
digit.
