On top of a standard emergency off (EMO) button, the GSM-V can be shut down by a network PC, re- mote device or the system’s automated safety func- tions in the event of abnormal gas conditions.
Convergence of PCBs and EtherCAT I/O
All control and safety functions occur in real
time, due to the networking and I/O capabilities of EtherCAT industrial Ethernet technology. Stan- dardizing on the EJ series EtherCAT I/O system from Beckhoff, THE GSM-V contains an EJ1100 bus coupler, EJ1889 16-channel digital input, EJ3108 8-channel analog input, EJ4134 4-channel analog output and two EJ2809 16-channel digital output terminals. As an electrical engineer, Stetz appreciates
that he can attach the EJ series I/O terminals di- rectly to circuit boards, which eliminates point-to- point wiring. Stetz explains that the I/O terminals also preserved space. “With other vendors, I would need to have a box two or three times this size to incorporate so many I/O channels with off-the- shelf equipment. The fact that these terminals are so compact and easy to install on circuit boards gives AES greater flexibility in series pro- duction, and greatly minimizes the amount of wiring and potential for error,” he says. On top of these automation and
control products, the 16-gauge steel welded enclosure houses a number of components specific to ultra-high- purity gas delivery systems. These include eight configurable Form C relay outputs and eight solenoid valves, which can be expanded to 14, as well as an optional strain gauge conditioner and Type Z purge sys- tem. However, even with all of these scalability requirements, Stetz was able to retain a small section of un- used space in the ergonomically de- signed delivery system. “There is ac- tually a void on one side of the enclo- sure, so if I need to add another piece of hardware, I have the ability to do so,” he says.
Decreased Installation Time, Increased Power
The GSM-V gas delivery sys-
tem premiered at the SEMICON West 2017 trade show, and since then, AES has replaced obsolete GSM-5 units across the country. The system meets all required safety standards,

the GSM-V, we were replacing GSM-5 controllers with a different solution, and installation took at least a day, due to the number of required modifi- cations. We had to do a new panel cutout, drill holes and rewire many components with the older
replacement method,” Stetz says. “But with the new GSM-V, our field technicians can replace two in a day, and on occasion, we have completed three replacements in one day.” The success of the GSM-V proved significant
for AES and the SEMI-GAS division, and it caused the research and development team to identify other new and legacy systems that could benefit from automation and control products from Beck- hoff. The project showcased the ability of AES to adapt to the manufacturing environment of today, according to Murphy. “This was one of the products that helped de-
fine a clear vision for us to support our customers’ Industry 4.0 projects,” he says. “Many of our up- coming control solutions or upgrades to legacy sys- tems take into account the importance of cloud connectivity, data accessibility and compatibility with customers’ SCADA. The GSM-V provided an important step in this direction.” Contact: Beckhoff Automation, 13130 Dakota

including SEMI S2,
SEMI S8 and Uniform Fire Codes, and it offers greater functionality than its predecessor. It also offers two things very im-
portant to AES: a competitive price point and increased system flexibility. AES prides itself in being able to adapt standard product lines to spe- cific customer needs, and because the GSM-V is based on TwinCAT 3, the company can easily add any software that runs on a PC if necessary. “The Beckhoff solutions allowed AES to show our versatility, creativity and ingenuity with new products and legacy support, as well as the R&D for other new developments,” Stetz says. “This has only improved our standing with our customers.” While preserving the same di-
mensions and shape, the GSM-V does not retain the same cumber- some wiring requirements. The new system operates on a network con- nection through EtherCAT and power over a C13 cord, with the op- tion to hardwire the unit if the cus- tomer prefers it. This plug-and-play solution has cut installation times by 50 percent. “Until we finalized
