Azbil Corporation No. SS2-MGG41F-0100 - 5 - Network Parameters The following table shows the key parameter values that affect interoperability of the Fieldbus devices. The LAS needs to be configured to satisfy these parameters. If other devices on the same Fieldbus network require a greater number for them, the greater number must be used. This will degrade network performance, though. Note) . A LAS requires parameters other than those listed here to operate. Please refer to the user's manual that comes with your LAS device. . The T3 needs to be set between 15 seconds and 60 seconds. *1. unit: Octet time (256 s) *2. unit: Slot-Time Factory default setting Note) *3. If a specific Node Address other than 0xF8 is required, specifiy a PD TAG No. Symbol Parameter name Default value Range of Values V(ST) Slot Time *1 5 5 to 100 V(MID) Minimum Interframe Gap *1 10 10 to (V (MRD) -1) × V (ST), smaller than 120 inclusive. V(MRD) Maximum Response Delay *2 4 V (MRD) × (V (ST) shall be greater than 20 and V (MRD) shall be smaller than 11, inclusive.
