The user must enter data as detailed below:
CHASSIS – Logical chassis where the communication interface is installed. Range 1 - 29.
SLOT – this is the slot where the communications interface is installed. Range 1 – 12.
NETWORK_ID - Peer network number supported by this controller. Range 1 – 8.
SUBNET_ID - Subnet number within peer network supported by this controller. Range 1 – 8.
PEER_ID - Peer identity of this controller. Range 1 – 40.
RESPONSE_TMO – Milliseconds allowed for a peer to acknowledge a data packet. If this field
is set to zero, no acknowledgement is required. This field need only be specified as non-zero to
avoid network packet sequence errors in networks where the propagation delay between any
two nodes could exceed 1ms. Range 0 – 10000.
REFRESH_TMO - This represents the milliseconds a network controller will wait for a token
from the master before declaring the network inoperable and discarding any data awaiting
transmission. This time must be configured for both master and slave modes. Range 1 – 10000.
TX_DATA_TMO – This represents the milliseconds a network master controller will wait for a
slave to complete transmission of its data and return the token before declaring the slave
absent. This parameter will be ignored during slave mode. Range 1 – 10000.
Boolean output variable 1 – Peer Communications using this controller is started/stopped by
this Boolean output. TRUE = Controller enabled.
Boolean output variable 2 – Master / Slave setting for the controller. TRUE = Master, FALSE =
Slave.
