Chapter 4 Input/Output Instructions (MSG, GSV, SSV, IOT)
NAKReceiveLimit SINT GSV The number of NAKs received in response to a message before stopping transmission (point-to-
point communication only). Valid value 0...127. Default is 3.
NormalPollGroupSi
ze
INT GSV Number of stations to poll in the normal poll node array after polling all the stations in the priority
poll node array (master only).
Valid value 0...255. Default is 0.
PollingMode SINT GSV Current polling mode (master only). Default setting is 1.
Value Meaning
0 Message-based, but don’t allow slaves to initiate messages
1 Message-based, but allow slaves to initiate messages (default)
2 Standard, single-message transfer per node scan
3 Standard, multiple-message transfer per node scan
ReplyMessage
Wait
DINT GSV The time (acting as a master) to wait after receiving an ACK before polling the slave for a
response (master only). Valid value 0...65,535. Delay in counts of 20 msec periods. The default is 5
periods (100 msec).
SlavePollTimeout DINT GSV The amount of time in msecs that the slave waits for the master to poll before the slave declares
that it is unable to transmit because the master is inactive (slave only). Valid value 0...32,767.
Delay in counts of 20 msec periods. The default is 3000 periods (1 minute).
StationAddress INT GSV Current station address of the serial port. Valid value 0...254. Default is 0.
TokenHoldFactor SINT GSV Current value (1...4) of the maximum number of messages sent by this node before passing the
token on a DH-485 network. Default is 1.
TransmitRetries SINT GSV Number of times to resend a message without getting an acknowledgment (master and slave
only).
Valid value 0...127. Default is 3.
