1-4-4 I/O Status Data

Normal Flags

In addition to I/O data, the DST1-series Safety I/O Terminals support status data to check the I/O circuits. The status data includes the following data, for which remote I/O communications can be performed.

• Normal Flags (ON when there is no faults in the internal circuit and the external wiring)

• An AND Flag of the Normal Flags

• Output monitors (the actual output ON/OFF status)

Normal Flags indicates whether each safety input, safety output, or test output is normal (normal status: ON, error status: OFF).

The input reaction time and the output reaction time of the DST1-series Safety I/O Terminal are added to monitor the operation time.

Maximum input reaction time of the DST1-series Safety I/O Terminal = 16.2 ms + ON/OFF delay

Maximum output reaction time of the DST1-series Safety I/O Terminal = 6.2 ms + Relay reaction time (DST1-MRD08SI-1 only)

The measurement is accurate to ±6 ms. The user can monitor this information using the Network Configurator and

explicit messages.

Page 66

Maintenance Functions of DST1-series Safety I/O Terminals Section 1-7

Note • In the DST1-MD16SL-1 or DST1-MRD08SL-1, the time is measured

from when a safety output turns ON until the safety input turns ON for the safety input and safety output with the same number (e.g., Safety Input 0 and Safety Output 0).

• In the DST1-ID12SL-1, the time is measured between two safety inputs turning ON (e.g., Safety Input 0 and Safety Input 6).

• The operation time is stored when the time from an output turning ON to an input turning ON is measured. The measurement, however, continues internally until the next time the output turns ON. If the input turns ON again before the output turns ON, the measurement time will be updated. If an input occurs in the middle of the operating range of reciprocating motion, like a cylinder, the measurement value of operation (outward path) may be updated when returning (return path).

• When an output turns ON two consecutive times before the input turns ON, the time will be measured from the second time the output turned ON until the time the input turned ON.

Tens di

it of node address

If a node address between 64 and 99 is set, the node address can be set from the Network Configurator.

IMPORTANT • The node address must be set while the communications power supply is

turned OFF.

• Do not change the rotary switches while the power is ON. The DST1series Safety I/O Terminals will detect this as a change in the configuration and will switch to fault state.

• Use a small flat-blade screwdriver to set the rotary switches, being careful not to scratch them.

2-6 Configuration

Configure the DST1-series Safety I/O Terminals using the Network Configurator. Refer to Section 3 Configuration for details on settings. Refer to the Sys- tem Configuration Manual (Cat. No. Z905) for Network Configurator operating procedures.

3-2-3 I/O Data Supported by Each Model

The following tables show the I/O data supported by each model of the DST1series Safety I/O Terminals.

Refer to 3-2-4 I/O Assembly Data for data arrangements.

From among the I/O data, safety connections for up to four items, including one output, can be allocated for the Master Unit and standard connections for up to two items can be allocated for the Master Unit.

IMPORTANT Communications with up to 15 Safety Controllers for each connection can be

performed using multi-cast connection. If four connections are used, however, only a maximum of 30 Safety Controllers total can communicate with the DST1-series Safety I/O Terminals. Up to two safety connections can be used with the DST1-XD0808SL-1.
