Communication Data - SMC Networks ITV1000-IO Series Operation Manual

４．Pressure setting method and output monitoring
Pressure can be set by sending input data from the master PLC to the regulator where the F.S
is based on a 12 BIT resolution.
Do not operate the product outside of the specifications.
<Relationship between set data and pressure>
Output pressure
From the 16 BIT process data (2byte), input the 12BIT resolution starting from 3rd BIT to the
14th BIT.
Refer to the communication data for further details.
５. Communication data
5.1 Process data map
PD OUT (to ITV)
15*1 14 13
100% F.S.is indicated using 12 BITs, from the 3rd BIT to the 14th BIT.
*1 Setting up to 120% F.S is possible by using the 15th BIT (However this is out of warranty).
*2 Either 0 or 1 will have no effect.
PD IN (from ITV)
15*3 14 13
100% F.S. is indicated using 12 BITs, from the 3rd BIT to the 14th BIT.
*3 Setting up to 120% F.S is possible by using the 15th BIT (However this is out of warranty).
*4 0 is returned in an unused area.

Detection of the set pressure
BDC1
*It detects when the output pressure reaches within ±10% F.S. of the set pressure.
