TOSLINE-S20
The TOSLINE-S20 is a Local Area Network (LAN) for factory automation systems.
It can achieve high-speed data linkage between PLCs and communication between
industrial computers.
One T2 station can be mounted in any slot, in the same way as an I/O module.
SN221 and SN222A are allocated as optional card in the T2N.
Therefore READ/WRITE instructions should be used to access data of TOSLINE-S20
modules, because the link registers are not assigned.
SN221
(Co-Axial Cable)
SN222A
(Optical Fiber Cable)
Topology Bus
Transmission speed 2 Mbps
Transmission Distance 1km 10km
(1km between stations)
Number of stations Max. 64 stations
Response speed Minimum 5ms in scan transmission

TOSLINE-30
The T2N can use the TOSLINE-30.
It is effective when connecting EX series systems to the T2N.
Up to 4 T2 stations can be mounted in any slots, in the same way as I/O modules.
The link relay/register(Z/W) is assigned for the TOSLINE-30, the same as the
TOSLINE-S20LP. If the TOSLINE-S20LP is used together with the TOSLINE-30,
the link registers assigned to the TOSLINE-30 (starting with W0000) should not
allocate for the TOSLINE-S20LP.

DeviceNet (Scanner)
The DeviceNet is a field network. It can achieve data linkage between the T2N and
any ODVA certified devices.
The T2N can use the DeviceNet scanner module.
It is effective for connecting DeviceNet systems to the T2N.
The T2N stations can be mounted in any slots, in the same way as for I/O
modules.
